S) 1.0 Introduction

Foreword

Thanks to:

Louis Ohland  for all the parts he sent me and the FA
Q
submissions he still does.

Charles Lasitter , President of NC Direct Marketing,
919-286-0100.  He sent me a working PS/2 95 with monitor.  The merchandis
e was
extremely clean and in great condition, keep in mind this was a donation.
..I
am sure paying customers will recieve better equipment still (if that is
possible).  He truly was very generous and is knowledgible in PS/2's.  If

anyone needs anything I would contact him first.

There is no cost for this document.  Also anyone is free to reprint and
reformat it, including the conversion to HTML, as long as the content doe
s not
change.  I only ask that those who can send me something...sort of like
shareware.  I am now a Computer Science degree-seeing college student and
 to
maintain this document and answer the emails I recieve daily is a sacrifi
ce. 
I try to get in a two hour workout every other day and run 5 miles every 
other
day, as well as try to keep girlfriends happy, to work, attend class and 
study
somewhere in there also, oh and eat and sleep.

Things I need right now are:
o Pentium 200MMX chip for my aging main system, even a 166MMX or somethin
g  
  comparable and faster than my P133. It needs to be 3.3 volts.  My
motherboard supports
  50,60,66MHz speeds and 1.5, 2, 2.5, 3 multiplers.

o Drive rails for the PS/2 95.  I need 3 sets.

o SCSI CD-ROM Drive, any speed.

o 256k Cache module for the Model 95 for my Type 1 processor card.

o Larger than 4MB SIMMS for my Model 95.  I currently have 4MBx8 for 32MB

total, I would like
  8MBx8 for 64MB.  This will be a LINUX setup for my education.

o Of course cash donations are always accepted.

My address will be 3702 Old Lighthouse Circle, Wellington, Florida  33414.


Q) 1.1  What does this FAQ cover and how do I use this FAQ?

This FAQ is for the PS/2's and most other MCA machines.  There may be som
e
information that is inaccurate for non-IBM machines and this information
should be gathered from the appropriate manufacturer.  Also this is meant
 as a
supplement to the comp.sys.ibm.pc.hardware FAQ, although one could possib
ly
use only this document for probably 90%+ of PS/2 issues.  The c.s.i.p.h F
AQ is
full of information (over 300k I believe) that any PC-compatible owner ca
n use
almost everyday.  The PS2 FAQ (almost 300k by itself), therefore, tries t
o
avoid repeating what can be obtained via this FAQ or other FAQ documents 
which
are easily available. 

To use this FAQ easily, import it into any standard word processor and us
e a
global text search to find what you want.  For instance, on WordPerfect h
it F2
and enter the text you want to find and hit enter.  The section numbers f
rom
the table of contents make good search headings.  There are web-based ver
sions
(www.computercraft.com) of this document and although nicer for most, the
 idea
behind this FAQ is to give those with minimum ability access to the file.

If there are deficiencies, errors, and/or missing information you would l
ike
to see email me at: alkemyst@shadow.net


Q) 1.2  What are the different PS/2s and their features?
     Note: a very good reference can be found at ftp://ftp.simtel.com,
     in /.3/simtelnet/msdos/info/ps2-ref.zip (#25,30,50,55,60,70,73,80).

(Thanks Louis Ohland )

Stumbled across a reference document with a good overall description of t
he
four different complex types and their capabilities. I will get the link 
so
people can find the *.pdf also..

Some errata seemed to have snuck in- the DMA speed goes from 20 to 25MHz 
then
back again to 20MHz..

Original compiled by Roger Dodson, IBM. May 1996

The IBM Model 90, and Model 95, and PC Server 500 are unique in providing
 a
Processor Complex (adapter) that integrates the (1) processor, (2) memory

cache controller and L2 cache, (3) memory controller, (4) DMA controller,
 and
(5) I/O bus controller. This provides the capability to upgrade to new
technology by only replacing the Processor Complex.
Upgrading a processor along with the memory and I/O controller have a
significant effect on performance via a balanced, tuned system. Vendors t
hat
do NOT change memory and I/O controllers run the risk of having an unbala
nced
system that is not as efficient. There are four types of Processor Comple
xes
for these systems: Base or Type 1, 2, 3, and 4.

o   Processor Complexes are interchangeable among Model 90's, Model 95's,
 and
the PC Server 500.

* Any existing Model 90, Model 95, or PC Server 500 can be upgraded to a 
new
Processor Complex. For example, Base 1 to Base 2 or Base 3 or Base 4; Bas
e 2
to Base 4, etc. If "Upgrade" is listed above, then an upgrade option is
available.
All Processor Complexes withdrawn as of June 1996

e
  (256 KB write-thru standard with 486DX 50 MHz).
* No math coprocessor socket ("J", "K", and "Upgrade" models already have
 a
  math coprocessor as part of 486DX).
* 24 bit DMA; 10-12 MHz.
* Dual path memory design (Dual Bus Interleave). Allows both the processo
r
  and busmasters to access memory concurrently though two paths.
* 20 MB per second data transfer support (for MCA bus).

* Math coprocessor socket on "H" model only to add 80487 math coprocessor

  or to add a 486DX2 50/25 MHz upgrade chip which has an integrated math
  coprocessor.
* High speed 25 MHz DMA so that it is now synchronous with the 486; 24 bi
t    

  DMA.
* Faster bus arbitration (than Base 1) for busmasters to increase
  performance.
* Memory controller to support both interleaved (higher performance -pair
s
  of SIMMs) and non-interleaved memory (allows single SIMMs).
* 20 MB per second data transfer support (for MCA bus).

Base 3           "M"/ Upgrade 486DX 50 MHz        (announced April 1992)

Type 3
* 40 MB per second streaming data transfer support. This is an advanced
  Micro Channel I/O controller that provides faster data transfer rates t
o
  increase performance.
* Error Checking and Correcting (ECC) memory controller which will
  automatically correct any single bit errors on the fly (98% of memory
  errors are single bit); all 2 bit errors are found which halt system;
  some 3 and 4 bit errors are found which halt system; single bit errors
  are logged with optional software (NetFinity?) and multiple bit errors
  are logged in NVRAM.
* 256KB Level 2 memory cache (write-through) is standard.
* High speed 20 MHz DMA; 32 bit DMA so it can use DMA to directly address

  all memory; DMA supports Subsystem Control Block.
* Faster bus arbitration (than Base 1) for busmaster performance.
* Enhanced dual path memory design (Dual Bus Interleave).
  Although Base 1 allows both the processor and busmasters to access memo
ry
  concurrently through two paths, the Base 3 and 4 has buffers at both
  paths to provide better performance. Also the buffer on the adapter sid
e
  (I/O buffer) uses packet data transfers for writes. This means 16 bytes

  are collected and this packet is written in one cycle to memory as
  opposed to writing for every 4 bytes received (as with unbuffered
  systems).
* Subsystem Control Block enabled (see definition).
* Vital Product Data support. Allows software (LAN Network Manager, LAN
  Mgmt Utilities/2) to obtain a unique serial number (identifier) on the
  processor complex which is in ROM.
* Synchronous Channel Check support (see definition).
* Data bus parity support (see definition).
* A logging facility is provided (for ECC or system errors).

DEFINITIONS
Subsystem Control Block provides for the enhanced transfer of command, da
ta,
and status information between busmasters (and between busmasters and the

system processor) to give increased performance. Capabilities such as com
mand
chaining, data chaining, and block data moves frees the processor from wa
iting
for command completion before issuing the next command and frees the proc
essor
for other tasks while a busmaster operates in parallel. Adapters and devi
ce
drivers must support this feature (many do today).

Synchronous Channel Check support provides for the signaling of errors
synchronously with the transfer in progress. Adapters and device drivers 
must
be designed to support this feature (none do today).

Data bus parity support provides for the verification of correct data as 
it is
transferred between the processor and memory and over the Micro Channel. 
All
data moved between individual components on the Processor Complex use thi
s
feature (processor, memory controller DMA, Micro Channel controller). IBM

Q) 1.3  What are the IBM brand MCA cards?

These are usually denoted with a /A suffix.  Here is a list of what is
current.

See Appendix A for full list.


Q) 1.4  Where do I get a Reference Disk for my PS/2?
[Rewrite by Aron Eisenpress ]

Reference Disks can be downloaded from two IBM sources, via ftp to
ftp.pc.ibm.com or by dialing the IBM PC Co. BBS at 1-919-517-0001.  The s
ame
reference disk files are available from both sources, but the BBS also ha
s
many other files, such as product announcements, reference and configurat
ion
information, some shareware and employee written programs, and many OS/2
related files.

Via ftp, follow these steps:
o Ftp to ftp.pc.ibm.com and log in as "anonymous" with your e-mail addres
s
  as the password.
o Select the "pub" directory, type:  cd pub [enter]
o Select the "pccbbs" directory, type: cd pccbbs [enter]
o If you don't know which file you need, look in allfiles.txt in the pub 
  
  directory; which includes short descriptions (also in this FAQ).
o The Reference Disk files are in the refdisks directory, type cd refdisk
s.
o Set transfer mode to binary, type bin [enter]
o Get the file you need, type get RFxxxxxxx.DSK (or whatever filename)
o If the Filename ends in .DSK you will need LDF.COM and if it ends in .T
G0
  you will need TGSFX.COM.
o Get back to the pub directory, type: cd .. [enter], cd .. [enter]
o Go to the UTILS directory, type cd UTILS [enter]
o Type: bin press return and then type: get LDF.COM or get TGSFX.COM [ent
er]

Via the BBS, follow these steps:
o Log on to the IBM PC Co. BBS at 1-919-517-0001. Follow instructions unt
il
  you get to the main menu.  Type REF DISKS, read the agreement and answe
r
  it.   Now you have access to directories 27 (ref disks) and 32 assuming
 you
  agreed.
o Type D to download then enter the filename.  Also LDF.COM or TGSFX.COM 
as
  outlined in the ftp directions.

After the files are obtained:

For .DSK files:
o Run LDF.COM so that the files LOADDSKF.EXE and PRODAID.TXT are
  extracted.  LOADDSKF.EXE is what you need, PRODAID.TXT is the IBM
  agreement.
o Insert a blank disk and type LOADDSKF filename.DSK A: (or B:) [/F to fo
rmat
  and /C to convert a 720KB image to a 1.44MB disk.]
o Ensure the proper disk is inserted and answer: "Y".
o Your reference disk is ready to go.

For .TG0 files:
o Run TGSFX.COM so that the files TELEGET.EXE and TGCONFIG.EXE are
  extracted.
o Run TGCONFIG and follow the prompts.

For more information on this procedure:
o On ftp, cd to UTILS and get DSK.HLP.
o On BBS, type HELP and read the instructions.

One other common source from dealers or IBM is the IBM "Technical Connect
ion
Personal Systems" CDROM.  Some offices also have one (a good sign is if t
here
are a lot of PS/2s in your office).  It also includes some files unavaila
ble
from the on-line sources.

Also check http://www3.ncr.com/support/pc/pcdesc/library/adfs.shtml

Also QBMCA on http://members.aol.com/mcapage0/mcaindex.htm can tell you w
hat
ADF you need.


Q) 1.5  Which file is my Reference Disk?  They are all cryptically writte
n.

See Appendix B.


Q) 1.6  What does the Reference Disk do?

The Reference Disk is your access to the internals of the PS/2, much like
accessing CMOS on other computers.  From the Reference Disk you can add
options, change the time and date, set up a configuration, check SCSI dev
ice,
change the settings of the options you added and test your system for
problems.  Once you have the Reference Disk running go to the Main Menu a
nd
Backup the Reference Disk and take one copy BEFORE you add options to it 
and
put it in a safe place.


Q) 1.7  I hear there is more diagnostics hidden on the Reference Disk,
        where are they?

This little known command allows one to test the system one test at a tim
e.
This is useful if the system hangs or gets an error early in the full-tes
t. To
access the Advanced Diagnostics press -A from the Reference Disk Ma
in
Menu and it will allow you to select which test to perform after verifyin
g the
present configuration.  Also these are more through tests and also offer 
hard
drive formatting options and some wrap plug port tests (see Q6.6 for deta
ils).


Q) 1.8  Why can't I copy my Reference Disk, I want to make a backup?

You can by selecting the option to backup the Reference Disk from the
Reference Disk Main Menu.  The files are written in a special way to the 
disk
and only the Reference Disk and LOADDSKF can create new/backup Reference 
Disks
unless a total disk copy program is used to copy the hidden files, DISKCO
PY
works.


Q) 1.9  I got the Reference Disk, but now it is saying I need an Option
        Diskette/or giving me a 165 error at POST...What are Option Diske
ttes
        and Where do I get them?

Option Diskettes are the .ADF files that allow the PS/2 to communicate
properly with installed options and the 165 error code is also saying tha
t the
proper .ADF file was not used to configure the system.  The BBS and
ftp.pc.ibm.com both have all the IBM option diskettes and some common thi
rd
party ones.  A file index of all the files on the ftp site can be obtaine
d by
getting the FILES.TXT file which has 100k of disk name and descriptions o
f
every disk IBM included with option, computers, and devices as well as so
me
third party software.  When you get the right one go to Copy an Option
Diskette in the Reference Disk Main Menu and it should do the work for yo
u.
Now just configure the system and you should be set.


Q) 1.10  I got the Option Diskette, but the Reference Diskette is telling
 me
         no option files can be found, What am I doing wrong?

Nothing usually.  Sometimes the Reference Disk can not copy the proper fi
les,
so look in the manual for the device and see what file(s) must be copied
manually over to the Reference Disk.  As always use a backup copy of the 
Ref
Disk.


Q) 1.11  I bought my PS/2 second hand who can I get technical support fro
m?

IBM.  The 800-772-2227 (1-800-PS2-2227) is open 24 hours a day for warran
tied
systems; however; there is no PS/2 models still under warranty so you wil
l
have to use the 1-900-555-2582 number.  They bill at $1.99 per minute the
 last
time I called (10/27/98).  Usually the staff is dead accurate and only ra
rely
is misinformation handed out.  However, the chances of misinformation is
greatly increased when calling during non-standard EST business hours as 
I
have experienced at 3am calls from the East Coast.

It seems lately I have been getting emails for people who have called the
 900
number, but could not get there questions answered.  This is not to fault
 IBM,
it simply is not practical to train your people on every machine released
, but
do I get to collect the 900 charges you the questions I answer? :).


Q) 1.12  IBM tech. support says they do not know my answer now what?

Well if they didn't connect you to the premium support section ask to be
connected there.  The Premium (I think that is what they call it) support
techs are usually a lot more adept at in-depth tech help, but sometimes t
he
normal tech does not connect you to them when you have a more advanced
problem so ask for them if you feel the person helping you is lost (usual
ly
symbolized by a lot of being put on hold 'while I find out the answer' ty
pe
responses).  Also it is a good idea to always call back later to double
check on things that you are not totally comfortable with the given answe
r.
Since these calls are no longer free it may not be practical to call back
. 
Also I am not sure the still have normal and Premium support since the ph
one
support has changed to the 900 number system, but of course, you can alwa
ys
email me.


Q) 1.13  Where can I find support on the internet?

Q) 1.14  I got an IBM MCA card with no labeling, How do I tell what it is
?

This is a big problem with IBM cards.  Most card manufacturers get label 
crazy
silk-screening their name and the card's name all over the card's
breadboard,yet IBM being the marketing giant doesn't need the extra produ
ction
step and goes with bare breadboards.

The first thing to do is to ground yourself (by touching the power supply
 of a
turned OFF computer is a good way) and try to set the card on an anti-sta
tic
bag or surface and try not to move around to much because one static char
ge to
a key area and it won't matter what the card is for.  Then try and find o
ut
what IBM part numbers (IBMPN) and FRU (Field Replacement Unit)(IBMFRU) ar
e
listed on the front and back of the card.  Contrary to popular belief you

cannot tell what the card does by these numbers as a class, i.e. not all
87Xxxxx cards are disk controllers and made in 1987.  With all the number
s
written down place the card in a anti-static bag and store it carefully. 
 Call
IBM at 1-800-772-2227 (or 900-555-2582 at $1.99/min) and ask them first. 

Chances are if the card is over two years old it is going to be a gamble 
at
best.  If they could not help, it is time to post your problem to
comp.sys.ibm.ps2.hardware for answers.  Try to render an ASCII image of t
he
card to give people an idea of what it is and this might also help someon
e
identify it on the spot.

Also the FCC# could be used as it almost never changes and is unique for 
each
card.  The FCC website is www.fcc.gov/oet/fccid.  There is also SBS Direc
t's
FCC ID Look-up at www.sbsdirect.com/fccenter.html.  Lately these have pro
ven
excellent resorts though sometimes the descriptions given are vague you a
t
least will know the manufacturer and purpose of the card.

Another method though I believe you need to have it installed and configu
red
is a program on PC-DOS 6.3 which takes the 'electronic name' (POSID, a fo
ur
digit

S) 2.0 Motherboards

Q) 2.1  Where can I find a PS/2 motherboard?

PS/2 last a long time, but sometimes due to mother nature, the user or ju
st
age the motherboards (planar boards in IBM-speak) fail.  These can be obt
ained
in many places both new and used.  Beware that the price of a new motherb
oard
is steep from IBM. Some third-party dealers have them much cheaper than i
n the
past.  DakTech carries them still in either new or as good as new form wi
th a
warranty, the Model 80-Axx series 25MHz motherboard with cache was only $
99
(10/27/98), there number is 800-325-3238.  Used motherboards could be obt
ained
from Page Computers 800-886-0055 for a reasonable price ($139.00 for a Mo
del
80-Axx w/ 90 day warranty).  I have bought two boards from them and have 
had
no problems with either.  The people working there are normally ex-IBM PS
/2
people who know a lot more than your average computer salvage types.  Tru
e
Blue Parts 508-833-2225 (trueblueparts@mindspring.com) formally Micro Mar
t has
the Model 80-Axx board for only $60.  Your best bet in general is to pick
 up a
Computer Shopper and scan the pages for PS/2 stuff and put the numbers in
 a
easy to find database (and also send new numbers found to me for FAQ
additions) so that whenever a problem arises you can look up the company 
that
sells what you need. 


Q) 2.2  Instead of a 'stock' motherboard can I get a more advanced board?

Reply Technologies sold new PS/2-type motherboards much cheaper than the 
IBM
versions.  These were high priced compared to normal PC-Clone motherboard
s,
but if you have cash in memory and PS/2 proprietary items it is cheaper t
han
replacing everything with new ISA/VLB/PCI based equipment. Also they offe
red
Pentium processors, the ability to use standard SIMMs, and even VLB.  The
se
are still available used and new from certain vendors, www.neointeractive
.com
is one such dealer. The types of motherboards available from IBM are the
486DX2/66 and 486BL2/66, and almost every 486 type from Reply Technologie
s. 
The IBM motherboards are only available from the Boulder Surplus Parts
division and are limited as they are no longer being made.  Also they wer
e
made only for the 60, 65SX, 70 and 80. 

There is a model 50/50Z and 55SX/LS planar board upgrade to 486SLC2/50
available currently from IBM.  Note: these were discontinued in Sept 94 s
o
they are limited, if IBM Direct doesn't have them call Boulder.

There are two versions of Reply's motherboards: the TurboBoard (for model
s 30,
50/50Z, 55SX, and 70) and the PowerBoard (for models     25/25-286, 30-28
6,
50/50Z, 55SX, 56 and 57, and 70).  Using the model 70 as the example, the

TurboBoard ($25.00) offers a 486SLC2 25/50 CPU, 387SX FPU socket, 16MB ma
x
using 3 70ns parity SIMMs, on board 1MB DRAM video, and 3 16 bit slots (o
ne
with video extension).  The PowerBoard ($95 with 486DX2/66) offers 486DX2
/66,
486DX4/100, or 586/100 with Intel Overdrive socket, 64MB max using 3 70ns

parity SIMMs, on-board 1MB (2MB+$25) 64 bit local bus video, two 32 bit a
nd
one 16 bit (with video extension) slots.  This is not a bad way to go. 
Processor upgrades are $25 for 486DX4/100 and $50 for 586/100.

The latest prices are as of 10/27/98 from Neointeractive
(www.neointeractive.com).


Q) 2.3  Will a standard motherboard work in a PS/2?

No...unless you are VERY lucky(and probably the only one in the world).  
Most
times the screw holes will not even come close, then the slots will be wa
y
off.  Even if you got it fastened into your case you would need a new pow
er
supply (which you would have to screw in some how) and then new floppy dr
ives
etc.  You are better off selling the system and starting from scratch.


Q) 2.4  What motherboards come with a cache and are more up-to-date with
        today's standards?

Well I am not going to be able to complete this section but the model 70 
and
80s with a 25MHz processor (8570/8580-Axx) come with a 64k L2 cache which
 is
very helpful.  Benchmarks on a 20MHz model 80 and 25MHz model 80 with the
cache showed Dhrystones at 4k for the 20MHz and at 7.7k for the 25MHz whi
ch is
a bigger difference than the 5MHz should give by itself.  As a matter of 
fact
a Cyrix DRx2-40 processor in a 20MHz machine gave only 8k Dhrystones, a c
ache
of some sort should always be obtained when purchasing a motherboard.


Q) 2.5  Which motherboards allow/prohibit additional on-board memory?

The following list shows what memory can be added.  The difference of the
 Max
System and Max Mother is what must be installed in the form of an expansi
on
card.

According to Louis Ohland 

Max mother is what can be physically added to the motherboard.  Max
system is what can be added in the form of memory cards.  Max
system is also the maximum memory of the mother and expansion card
combined.

To make it easier- The 90 / 95 machines do not support MME
(Matched Memory Extension) and therefor cannot accept add-on
memory cards.

With the advent of the type 4 complex, you have either 64MB max
with parity, or 256MB max with ECC (my 9595-OYT has 128MB..)(Maybe
someone can send me a Type 4 complex too  :)).


Q) 2.6  Can I use normal 72-pin SIMMs?  30-pin SIMMs?

Nope, neither.  There are reports of some using non-PS/2 72-pin SIMMs, bu
t
these have not been verified by myself and also I suspect that they are
actually third party PS/2 SIMMs the user was unknowingly using.


Q) 2.7  How do I tell the speed of the PS/2 SIMMs I have now on my
        motherboard?

Most of the times unless labeled it will be hard.  IBM's numbering system
changes all the time and many times the cross-reference can not be made. 
 I
got a SIMM here that has a nice label stating IBM  2M  85NS  P/N 68X6127
FRU 92F0104.  Now if that label were removed I would only have 89X8922 IB
M9314
L46056PE on the 18 chips that are attached to the SIMM, now if someone ca
n
make 2M or 85NS out of those three numbers I would be impressed as a call
 to
IBM showed it as not identifiable. 

In  OS/2 WARP there is a program that tells what is installed and the spe
ed of
the SIMMs.  This program is the system information utility.  Although it 
would
be impractical for a large amount of unlabeled SIMMs, a few can be ID'ed 
this
way.

According to Louis Ohland :

The 9595 Type 4 (possibly type 3) can report in setup on the speed
and architecture (parity or ECC) of each chip by slot...


Q) 2.8  What speed SIMMs do I need?

Unlike buying clone motherboards, the speed of the SIMMs you should need 
will
usually be easily found out.  For standard IBM, call IBM and for all othe
r
motherboard makers they should include it in their motherboard docs.  Mos
t of
the time the 80ns memory is the most common on the newer machines.  120ns
 was
used on the older PS/2s (i.e. 50's and 60's) and most 386s at or less tha
n
25MHz can get by with 85ns.  If you upgrade to one of the new 486 replace
ment
386 CPUs you will probably need 80ns memory unless stated that it will wo
rk
with normal system memory, 70ns and faster is probably a good idea and sh
ould
be used as 80ns and slower memory is becoming obsolete.

From Louis Ohland :

The 9595 Type 4 (possibly type 3) can report in setup on the speed
and architecture (parity or ECC) of each chip by slot...


Q) 2.9  How good is MCA and what does it offer?

IBM is pushing the MCA bus again.  It is possible to make it as fast as V
LB,
it comes close now.  The new 700 machines will offer a dual bus, MCA/PCI
which will give the best of both worlds.  The *BEST* thing about MCA is i
t
usually offers the PLUG-and-PLAY everyone wants, at least in most cases. 
 You
simply copy the .ADF files onto your reference disk then plug the new car
d in
and turn on your system.  The computer will figure out where the card is 
and
configure it and for once you don't have to set 10 banks of 8 dipswitchs 
with
a pen :).  Also it offers the best bus mastering out there.  A MCA card c
an
totally take over all functions of the CPU and FPU and cause no interfere
nce
with the rest of the machine, also a MCA board can have its own CPU to do
 the
work of the peripheral it is attached.  For example lets say you had a MC
A
Video Toaster type card...it could be set up to allow you to configure ce
rtain
options, enter data, then have it process the data no matter how complex 
and
return to your normal machine and witness no slowdown at ALL.  MCA allows
 card
functions to be totally independent and self-controlled.

A problem faced by ISA was device addresses, and ISA bus is only capable 
of
1024 device addresses while MCA can address 65,280.  Also, MCA has far mo
re
grounds along the bus preventing radio emission.   Lastly, MCA can share
interrupts while ISA can not.

The speed of MCA is something underestimated by non-PS/2 users.  It is a 
very
fast and quiet (as far as RF interference goes).  Some specs are:

     The maximum transfer rates on a 10 MHz MCA bus:

                                 16 bit MCA       32 bit MCA
     Normal transfers           10MBytes/sec     20 MBytes/sec
     (adr/data)

     Short Burst and Long
     Streaming transfers        20MBytes/sec     40 MBytes/sec
     (adr/data data data ..)

     Multiplex Streaming       (not available)   80 MBytes/sec
     (as above and uses the
      `idle' adr lines to
      transfer data as well,
      for a 64 bit transfer)

     Matched Memory Cycle                        21.3 MBytes/sec
     (matched memory cycle
      changes the timing of                     (32 MBytes/sec w/o
      the MCA bus to 62.5                        added wait state
      nanosec. for a 187.5                       at 62.5 Nanosec.
      4 byte adr-wait-data                       and 40 MBytes/sec

      is on a 16MHz model                        timing)
      80 as an example.)


[Originator: benker@hp-8.cae.wisc.edu]

Since there have been so many discussions about all of this, I'm posting 
the
OFFICIAL MCA specs.  These are direct from IBM.  MCA, as you will notice,
 has
the capability to be faster than even the local bus technologies with a
transfer rate of up to 160MB/sec.  Hope all of this helps.

The basic transfer cycle on the Micro Channel is a minimum of 200ns (100n
s
for the address and 100ns for the data which results in five million basi
c
transfer cycles per second for a device running in burst mode.  As shown 
in
Figure "Basic Data Transfer Mode", a data transfer operation is done in t
wo
steps.  First the address for the transfer (either I/O adapter or memory
location) is selected, then up to four bytes of data is moved across the 
data
buffer.

Depending of the width of the data path (8, 16, or 32 bits) the instantan
eous
data transfer rate on the channel would be 5, 10, or 20MB per second.  Th
e
matched-memory extension is a modification to the basic data transfer mod
e,
which can improve the data transfer capabilities between the system maste
r and
channel-attached memory.  When supported, it allows the basic transfer cy
cle
of 200ns to be reduced.

The DMA controller on the system board requires two basic transfer cycles
 to
move either 8 bits or 16 bits of data.  It moves the data from the origin
ator
to a buffer in the DMA controller and then to the target device or memory
location.  Because two cycles are used per 8 or 16 bits of data, the data
transfer rate for DMA controllers is 2.5MB or 5MB per second.  For blocks
 of
sequential data transferred over the Micro Channel, it should not be nece
ssary
to specify the address information more than once.  Both the source and
destination devices should update the address for each cycle by the size 
of
the transferred data.  This technique is supported by the Micro Channel a
nd is
known as streaming data mode (or streaming data procedure).  Using stream
ing
data mode with 32 bit transfer, the effective transfer rate is 40MB per
second.  The usage of the address and data buses during a data transfer u
sing
streaming data procedure is shown in Figure "Streaming Data Mode".

When the Micro Channel is running in streaming data mode, the 32 address 
lines
are only used during the first cycle of the transfer.  These address line
s are
therefore available for transfer of an additional four bytes during each
following cycle.  This mode is called multiplexed streaming data mode and

gives an effective width of 64 bits (8 bytes) for each cycle.  The result
ing
effective data rate is 80MB per second.  This is shown in Figure "Multipl
exed
Streaming Data Mode".

PS/2 Model 9595 (and possibly the 8595) can support the 100ns basic trans
fer
cycle with the SCSI Fast/Wide adapterrather than the current 200ns.  With
 the
current cycle the Micro Channel is able to transfer sequential blocks of 
data
with transfer rates of 20, 40, and 80MB per second.

Systems implementing the faster transfer cycle would be able to reach tra
nsfer
speeds of up to 160MB per second.  These rates are essential for advanced

function bus masters, which must move large blocks of sequential data.


Q) 2.10  Which is better, ISA/EISA/VLB/PCI/etc?

[From: ralf@wpi.wpi.edu (Ralph Valentino)]
[updated: alkemyst@shadow.net 10/23/94]

Here is a quick overview of the various bus architectures available for t
he PC
and some of the strengths and weaknesses of each.  Some terms are describ
ed in
more detail at the bottom.

XT bus: Bus originally used in the IBM XT.
        8 data bits, 20 address bits
        4.77 MHz

   Comments: Obsolete, very similar to ISA bus, many XT cards will work i
n
             ISA slots.
     
ISA bus: Industry Standard Architecture bus (a.k.a. AT bus)
        8/16 data bits, 24 address bits (16Meg addressable)
        8-8.33MHz, asynchronous
        5.55M/s burst
        bus master support
        edge triggered TTL interrupts (IRQs) - no sharing
        low cost

   Comments: Ideal for low to mid bandwidth cards, though lack of IRQs ca
n
             quickly become annoying.
     
MCA bus: Micro Channel Architecture bus
        16/32 data bit, 32 address bits
        10-20MHz, up to 40MHz could be possible, asynchronous
        80M/s burst, synchronous
        full bus master capability
        good bus arbitration
        auto configurable
        IBM proprietary (not ISA/EISA/VLB compatible)

   Comments: Since MCA was proprietary, EISA was formed to compete with i
t. 
             EISA gained much more acceptance; MCA is all but dead.

EISA bus: Enhanced Industry Standard Architecture bus
        32 data bits, 32 address bits
        8-8.33MHz, synchronous
        32M/s burst (sustained)
        full bus master capability
        good bus arbitration
        auto configurable
        sharable IRQs, DMA channels
        backward compatible with ISA
        some acceptance outside of the PC architecture
        high cost

   Comments: EISA is great for high bandwidth bus mastering cards such as

             SCSI host adapters, but its high cost limits its usefulness 
for
             Other types of cards.  Very commonly used in servers.

VLB: VESA Local Bus
        32 data bits, 32 address bits
        25-40MHz, asynchronous
        130M/s burst (sustained is closer to 32M/s)
        bus master capability
        will coexist with ISA/EISA
        slot limited to 2 or 3 cards typical
        backward compatible with ISA
        moderate cost

   Comments: VLB is great for video cards, but its lack of a good bus arb
iter
             limits its usefulness for bus mastering cards and its modera
te
             cost limits its usefulness for low to mid bandwidth cards. 
             Since it can coexist with EISA/ISA, a combination of all thr
ee
             types of cards usually works best.
             
PCI:  Peripheral Component Interconnect
        32 data bits (64 bit option), 32 address bits (64 bit option)
        up to 33MHz, synchronous 
        120M/s burst (sustained) (240M/s with 64 bit option)
        full bus master capability
        good bus arbitration
        up to 6 peripherals
        auto configurable
        will coexist with ISA/EISA/MCA as well as another PCI bus
        strong acceptance outside of the PC architecture
        moderate cost

   Comments: Combines the speed of VLB with the advanced arbitration of E
ISA.
             Great for both video cards and bus mastering SCSI/network ca
rds.

VL 2.0: Video Local Bus version 2.0
        64 data bits, multiplexing and data buffering
        up to 50MHz
        est. 400M/s burst
        full bus mastering
        good bus arbitration
        specification not completed yet

               3DTerms3D

Auto configurable:  Allows software to identify the board's requirements 
and
                    resolve any potential resource conflicts (IRQ/DMA/add
ress
                    /BIOS/etc).

Bus master support:  Capable of First Party DMA transfers.

Full bus master capability:  Can support any First Party cycle from any
                             device, including another CPU.

Good bus arbitration:  Fair bus access during conflicts, no need to back 
off
                       unless another device needs the bus.  This prevent
s
                       CPU starvation while allowing a single device to u
se
                       100% of the available bandwidth.  Other buses let 
a
                       card hold the bus until it decides to release it a
nd
                       attempts to prevent starvation by having an active

                       card voluntarily release the bus periodically ("bu
s on
                       time") and remain off the bus for a period of time

                       ("bus off time") to give other devices, including 
the
                       CPU, a chance even if they don't want it.

16Meg addressable:  This limits first party DMA transfers to the lower 16
 Meg
                    of address space.  There are various software methods
 to
                    overcome this problem when more than 16 Megs of main
                    memory are available.  This has no effect on the abil
ity
                    of the processor to reach all of main memory.

Backward compatible with ISA:  Allows you to place an ISA card in the slo
t of
                               a more advanced bus.  Note, however, that 
the
                               ISA card does not get any benefit from bei
ng
                               In an advanced slot, instead, the slot rev
erts
                               To an ISA slot.  Other slots are unaffecte
d.

The MCA specs at 10MHz show sustained throughput very close to VLB and 20
MHz
MCA specs should be equal or superior to VLB, however, usually MCA cards 
do
not operate at these faster speeds of 20MHz.

Q) 2.11  Will an ISA card work in an MCA (PS/2) machine?

No, they will not.  MCA, unlike EISA and VLB, is not backward compatible 
with
ISA.


Q) 2.12  How do I enter the CMOS configuration menu?

If it is possible on your machine it is Ctrl-Alt-Ins after Ctrl-Alt-Del. 
 If
nothing happens when you hit Ctrl-Alt-Ins at the prompt then you must use
 the
reference disk to change CMOS values.

From Louis Ohland :
With the type 4 complex, you can hit Escape for quick boot (bypass memory

check)
and/or hit F1 to run setup.


Q) 2.13  What is bus mastering anyway?

Bus mastering is the ability of the MCA card to directly read and write t
o
main memory.  This allows the CPU do delegate I/O work out to the cards,
freeing it to do other things.  If you want a bus mastering card, you sho
uld
specifically request it and expect to pay more.  Also not all cards are
available in bus mastering form due to the fact that they do not have to 
be
independent to the rest of the system, and some because they can't be
independent.


S) 3.0 IO controllers/interfaces

Q) 3.1  How do FM/IDE/MFM/RLL/ESDI/SCSI interfaces work?

Ok, first FM, MFM, and RLL refer to the data encoding.  Almost all drives

today are RLL.  IDE, ESDI, and SCSI are types of interfaces and the drive
s
that run on them.  The descriptions below will contain a lot of techno-ba
bble
to most, but the purpose of this is to give an idea how they work and in 
that
capacity the text below should suffice.  UPGRADING AND REPAIRING PC'S by 
Scott
Mueller describes this much better as that is the purpose of his book, no
t
this FAQ.

FM, or Frequency Modulation, was the earliest scheme.  Known as Single De
nsity
by many because of the floppies it was originally used on.  This was popu
lar
in the 1970's, but with a limit of about 80k it quickly died out.

It is the simplest way to encode zeros and ones.  Also to prevent sync er
rors
in long streams of zeros or ones, two transition cells are used per bit. 
 A
data cell representing the zero or one and a clock cell representing what

amounts to the position or record.  In a data transition cell, either a o
ne
bit is recorded to indicate a flux reversal or a zero bit to indicate non
e.
The clock cell is used for each bit also.  So each time you change bits, 
the
clock cell reverses flux.  This works great except for the fact that you 
lose
half your storage capability since each data bit requires two flux revers
als,
one for the data and one for the clock.

Example of FM Data to Flux Transitions
Data Bit     Flux encoding
1            TT
0            TN

T3Dflux transition
N3Dno flux transition


MFM, or Modified Frequency Modulation was created to reduce this overhead
 and
compact more data into the same space.  This was done by reducing clock
transition cells.  A clock transition cell is only recorded if a zero bit
 is
preceded by a zero bit.  This amounts to twice the efficiency and is why 
MFM
became known as Double Density (as did the disks which were originally
formatted this way).  It is still used in almost all PC floppy drives tod
ay. 
MFM is also twice as fast as FM.

Example of MFM Data to Flux Transitions
Data Bit            Flux encoding
1                   NT (no clock cell encoding)
0 preceded by 0     TN (clock cell encoded)
0 preceded by 1     NN (no clock cell encoded)


RLL, or Run Length Limited, is today's method of choice.  RLL stores 50% 
more
data than MFM and three times the data of FM.  In RLL, groups of bits are

taken as a whole and combined to generate a pattern of flux reversals.  B
y
combining the clock and data cells into these patterns, the clock rate ca
n be
increase while keeping the same distance of transitions on the disk.

RLL was invented by IBM first for mainframes, but by the 80's this techno
logy
flowed into the desktop PC's of the day and is still a viable encoded sch
eme. 
RLL gets its name from the two main functions of the patterns stored.  On
e is
the minimum number (the run length) and maximum number (the run limit) of

transition cells allowed between two actual flux transitions.  There are
several schemes to this, but RLL 2,7 and RLL 1,7 are the most popular wit
h 1,7
used almost exclusively in all large drives.

Using RLL 2,7 as the example, the numbering scheme is based on the fact t
hat
there can be as few as 2 and as many as 7 transition cells separating two
 flux
transitions. Also, FM and MFM can be referred by RLL naming conventions a
s RLL
0,1 and RLL 1,3, respectively, however when they are discussed it is stil
l by
there original FM and MFM names. 

Example of RLL 2,7 Data to Flux transitions
(Using IBM's ENDEC (ENcode/DECode) table only as there can be unlimited
variations to this encoding scheme)
Data          Flux encoding
10            NTNN
11            TNNN
000           NNNTNN
010           TNNTNN
011           NNTNNN
0010          NNTNNTNN
0011          NNNNTNNN

Example of the character "X" (01011000 in binary) showing the actual way 
it is
encoded on disk.
FM:      Bit  .0.1.0.1.1.0.0.0
         Flux TNTTTNTTTTTNTNTN 11 transitions
MFM:     Bit  .0.1.0.1.1.0.0.0
         Flux TNNTNNNTNTNNTNTN 6 transitions (50% of FM)
RLL 2,7: Bit  .0.1.0.1.1.0.0.0
         Flux TNNTNNTNNNNNNTNN 4 transitions (30% of FM)
T3DTransition flux, N3DNo Transition flux, and .3Ddata bit boundary.

Also there is a new encoding scheme called PRML, Partial-Response,
Maximum-Likelihood that compacts data a further 40%.  This uses DSP techn
ology
to clean the signal of noise and allow data to be stored closer together,

whereas the other three still have the same density of flux transitions.

Now on to interfaces.  There are a few:  ST-506/412, ESDI, IDE, and SCSI 
as
well as the variations of each (SCSI-2, ATA-2, etc).  The interface trans
mits
and receives data to and from the drive.  Only the ST-506/412 and ESDI ar
e
true disk-controller to drive interfaces.  SCSI and IDE are system level
interfaces usually containing ST-506/412 or ESDI internally.  SCSI adds a
n
extra level of interface that attaches directly to the system bus whereas
 IDE
is a direct bus interface.

ST-506/412 - developed by Seagate back around the beginning of the 80's a
nd is
named after the 5MB ST-506 drive and 10MB ST-412 drive originally attache
d to
this interface.  This was the interface of choice for almost all drive
manufacturers during this time period.  Also interestingly enough all dri
ves
using this interface were plug-and-play as long as the BIOS on the system

board supported the drive (when the IBM AT was introduced IBM removed the
 BIOS
off the ST-506/412 interface and included it into the IBM AT system BIOS)
. 
This interface is obsolete by today's standards, though it endured a long
 time
for an interface designed around a 5MB drive which at the end of its life
 was
connected to drives as large as 233MB!  Using two Drive Select (DS) chann
els
you could have up to two drives attached to this controller, DS1 was the 
C
drive and DS2 was D.

ESDI, Enhanced Small Device Interface - developed in the early 80's by Ma
xtor
to succeed the ST-506/412 standard and provide more performance and later

adopted by ANSI.  Offered enhanced reliability by incorporating a ENDEC i
nto
the drive.  Capable of 24 megabits/sec, though limited to 10-15 megabits/
sec
by almost all drives.  ESDI drives were not always compatible with other 
ESDI
drives due to implementation deviations between manufacturers and this op
ened
the way for the IDE standard which though slower was much cheaper to prod
uce. 


ESDI also allowed for automatic drive configuration and defect mapping
(sometimes).  Also mostly compatible with the ST-506/412 interface in tha
t if
the system supported one, it usually would the other.  Sometimes addition
al
software would need to be run (for auto defect mapping as an example).

IDE, Integrated Drive Electronics - a generic term for any drive with bui
lt-in
controller electronics.  Though more often applied to ATA (AT Attachment)

drives and is an ANSI standard.  These were originally exclusively Hardca
rds
where a small 3.5" ST-506/412 or ESDI drive was mounted directly to the
controller card.  More reliability due to the lack of ribbon cables and
reduced noise. 

Although the IDE cable ports are on the motherboards of today's computers
, the
actual controller is still in the drive.  The port is only used to connec
t the
controller to the bus and is actually a 40 pin subset of a 98 pin ISA slo
t. 
Having the controller built-in to each drive is why many times IDE drives

don't work together.  Both controllers compete to be the Master despite
assigning it a Slave status sometimes.  The usual workaround is to use ID
E
drives by the same manufacturer and also of the same specification.

PS/2 content:  in 1987 IBM offered IDE drives for MCA machines called MCA
 IDE
(a 16 bit device like ATA IDE).  These were connected to the bus thorough
 an
interposer card and needed only a few buffer chips and almost no circuitr
y
which is why they are referred to as paddle boards by many (game
paddle/joystick boards have very little circuitry also).  An 8 bit variat
ion
made it into the non-Microchannel Model 30 similar to XT IDE.

IDE drives offer the highest performance at any cost for a single user, s
ingle
tasking operating system.

ATA-1 was introduced in 1989 and ATA-2 (EIDE by Western Digital and Fast-
ATA
and Fast-ATA-2 by Seagate and Quantum) in 1995. 

ATA-2 allows for drives larger than 504MB by translation (basically alter
ing
the perceived geometry of a drive to other programs which cannot handle m
ore
than 1024 cylinders.  A 2000 cylinder drive with 16 heads would be transl
ated
as a 1000 cylinder drive with 32 heads). Translation methods rely on an
enhanced BIOS and are known as Standard CHS (Cylinder Head Sector), Exten
ded
CHS or Large, LBA (Logical Block Addressing). 

It also allows faster data transfers with PIO (programmed Input Output) m
odes.
 Mode 0 has a 600ns cycle time and limits transfers to 3.3MB/sec.  At its
 best
ATA-1 had a 240ns cycle time and transfer rate of 8.3MB/sec.  With ATA-2 
in
PIO mode 3 with its 180ns cycle time, transfer rates go to 11.1 and with 
mode
4 and a 120ns cycle the rate is 16.6MB/sec.  This implementation requires
 the
port to be a local bus port (VLB or PCI).  Also despite support for two d
rives
usually only the primary can support up to mode 4, the secondary is actua
lly
connected through the ISA bus and is limited to mode 2.

DMA (direct memory access) can also be used to exclude the CPU from the d
rive
to bus transfers using the system boards DMA controller to handle the
transactions.  Busmastering DMA controllers use their own DMA controller 
to
handle this and because of the extra complexity it drives up the cost.  D
MA is
never used efficiently with an ISA bus, but with today's PCI boards speed
s of
33MB/sec are now common.

SCSI, Small Computer System Interface - not really a disk interface, but 
a
system-level interface.  SCSI is a bus that supports up to eight devices.
  One
of these is the host adapter and the gateway between the SCSI and PC buse
s. 
The SCSI bus does not talk directly to the devices either, but to each de
vices
controller built into it (Most SCSI drives are actually IDE drives with S
CSI
bus adapter circuits added.  Each device is given a SCSI ID.  Up to 4 hos
t
adapters can be supported by most systems and with each able to control 7

other peripherals that gives a total of 28 devices.  Some newer SCSI
implementations can support 15 devices per bus.

The SCSI standard like ESDI is a hardware standard.  It does not specify 
how
communication is to be handled and as a result some SCSI devices are not
compatible with others.  Scanners and some CD-ROMS fall into these catego
ry as
they do not include the BIOS for self-booting hard drives.

There are several implementations of SCSI.

SCSI-1 included many features and commands, but listed them as optional s
o
many were not used causing incompatibility galore.  SCSI-1 was limited to

5MB/sec transfers.  SCSI-1 devices were 8 bit.

SCSI-2 fixed this by requiring 18 commands to be coded, a Common Command 
Set
(CCS).  SCSI-2 also brought support for CD-ROMS, tape drives, and other
devices.  There was Fast SCSI-2 and a 16 bit version called Wide SCSI-2.

Fast synchronous SCSI and Wide SCSI were an optional specifications and r
aised
the transfer rate to 10MB/sec when each was used by itself.  However, fas
t and
wide can be combined and raise transfer rates to 20MB/sec.  There was als
o a
32 bit specification defined, but was not implemented as being too expens
ive.


Q) 3.2  How can I tell if I have MFM/RLL/ESDI/IDE/SCSI?

Open the computer and check the model number of the drive and contact the

manufacturer is the only way to be 100% certain in many cases.

That aside, the first thing to check is the number of pins on the drive's

connector(s) and how many cables you have. The second thing to check is t
he
CMOS setup, assuming, of course, that it is in a working system.

ST-506/412 3D two or three cables (1 drive or 2 drives): two 20 pin, and
 one
             34 pin if two drives are connected (do not attempt to connec
t an
             ESDI drive to these cables, although it will attach the sign
als
             are different).
           
             17 (MFM) or 26 (RLL) sectors per track.

             One 34 pin cable is daisy-chained between up to two drives m
uch
             like floppies, though due to different twist in the cable th
ey
             are not interchangeable.  Many of these interfaces include a

             provision for connecting floppies though. 
            
             A terminating resistor is used if only one drive is connecte
d.

ESDI 3D 2 cables: 34 pin and a 20 pin (as stated in the ST-506/412 secti
on both

       the 34 and 20 pin are identical in looks to the cables that are us
ed
with
       the ST-506/412 interface, but do not connect a MFM or RLL drive to
 this

       interface).

       usually set up as type #1 in the CMOS and auto-configured at boot 
time

       32 sectors per track or more and almost always 1:1 interleave givi
ng
       up to 1MB/sec transfer capability.

IDE 3D 1 cable: 40 pins with three pin-header style connectors on it.  O
ne
      plugs into the IDE interface connector and the other far end into t
he
      primary drive (usually...sometimes this is the secondary), followed
 by
      the secondary being connected in the middle (again it is possible t
he
      primary is in the middle).

      Sectors, heads and tracks are variable.

        CMOS does not determine accurately.

SCSI-1 3D 1 cable: 50 pins
SCSI-2 3D 1 cable: 68 pins
         PS/2 uses 60 pins so I am not sure if there is a way to tell bet
ween 
 
         SCSI-1 and SCSI-2 on a PS/2

         Aftermarket controllers use the standard 50 pin and some use the

Apple
         SCSI connector for external drives.

         usually set up as "not installed" in the CMOS


Q) 3.3  Why won't my two hard drives work together?

IDE:  (Assuming the user has determined that the Master/Slave arrangement
s are
correct).  IDE drives of different makes may just be incompatible, likewi
se
occasionally different models of the same manufacturer are.  Try two iden
tical
drives, swapping master and slave, or trying a combination of a third dri
ve
with any of the other two and the problem should usually cease.

SCSI:  (Again assuming the user understands how to configure a SCSI adapt
er). 
If using SCSI-1 spec drives, there just may be incompatibilities between 
them,
try another drive preferably of the same manufacturer or better yet an
identical drive.  With later SCSI specifications, chances are something i
s not
terminated or ID'd properly.  Try changing the order.


Q) 3.4  How do I install a second controller?

Simply pull it in and boot with the reference disk and viola. Of course i
t is
never this easy.  Occasionally some controllers are incompatible with one

another and it is impossible to get them to work together.  For this reas
on
try to keep controllers identical (use the same manufacturer at the very
least).


Q) 3.5  Which is better, SCSI or IDE or ESDI?

Again like the MCA versus ISA/EISA/VLB/PCI debate.  There is what is bett
er in
theory and what is better in real life.  ESDI is a dead standard with muc
h
faster and larger capacity, cheaper IDE drives out there, though it had t
he
possibility of being the fastest.  Unfortunately in the PS/2 arena you us
ually
can't chose IDE which with the newer versions offers almost all of the sp
eed
of the best SCSI drives and still is the fastest single user, single task
 OS
drive there is.  SCSI, however, with multitasking operating systems shine
s,
especially the later Fast/Wide standards.  Though I do not know of any PS
/2
controller capable of the 40MB/sec and 80MB/sec of today's top SCSI drive
s the
10-20MB/sec performance is more than enough for many desktops.


Q) 3.6  Can MFM/RLL/ESDI/IDE and SCSI coexist?

The PC is limited to two drive controllers total.  SCSI, however, is a "h
ost
adapter" and not a drive controller.  To the rest of your system, it appe
ars
more like an Ethernet card than a drive controller. For this reason, SCSI
 will
always be able to coexist with any type dive controller.  The main drawba
ck
here is that on most systems, you must boot off a disk on the primary dri
ve
controller, if you have one.  That means if you have SCSI and IDE in your

system, for example, you can not directly boot from the SCSI drive.  Ther
e are
various ways to get around this limitation, including the use of a boot
manager.

MFM and RLL are the methods of writing the data to the disk and as such a
lmost
always exist together (MFM for the floppy drives and RLL for the fixed di
sks).


Q) 3.7  What's the difference between SCSI and SCSI-2? Are they compatibl
e?

The main difference between SCSI and SCSI-2 are some new minor features t
hat
the average person will never notice.  Both run at a maximum 5MB/s.  Thou
gh
Fast and Wide SCSI-2 double this speed and can be combined to quadruple i
t.
All versions of SCSI will work together (SCSI-1 in compatible with SCSI-1
 only
in theory as there was no set command set, however, I have never experien
ced
such an incompatibility).  On power up, the SCSI host adapter and each
device(separately) determine the best command set and the speed that each
 is
capable of.

For more information on this, refer to the comp.periphs.scsi FAQ.


Q) 3.8   Can I use a non-IBM ESDI in a PS/2?

[From: helling@uwindsor.ca ]

FORMATTING A NON_IBM ESDI DRIVE FOR A PS/2 80.

Well, it might have been impossible for me to put a simple MFM
hard drive into my model 80 PS/2, 4M, model 8580-111, but I
did get a NON-IBM ESDI drive installed, using a PS/2 ESDI
controller, and the following patched version of LLFORMAT.COM,
usually found on the 7080 reference disk....

First: a rumor that the following PS/2 80's LIKE MFM and ESDI:
041,071,111,311
and the following, which supposedly came with SCSI don't...
121, 161, possibly AXX...
This is unconfirmed, and mine is a 111, so it worked....

1) In dos, go to your ref disk, make a directory called SPARE,
copy LLFORMAT.COM to it (nice safe backup copy)
1a) Copy the dos DEBUG.EXE program onto the ref disk...

Now follow this, paying attention to my comments...

: >3. This DEBUG procedure has been documented by Tillman Schmidt of
: >   Koeln, Germany following the translation of an article in the
: >   German c't Magazin fr Computertechnik, issue 5/1991, page 272f.

The reference-disk comes with a program to low-level-format a hard disk:
LLFORMAT.COM; boot from the reference-disk and press CTRL-A in the main m
enu
to get a menu for extended diagnose. To low-level-format a non-IBM-disk,
you have to patch llformat.com with debug as described below.

LLFORMAT.COM doesn't format a non-IBM-hard disk, because there is a
defect-map (info about defect blocks) on the cylinder before the last on
IBM-disks. But llformat.com only calls a BIOS-routine via INT 13h, where
one can set a flag to ignore the defect-map (set bits 0,1 in CL-register)

Here is the reference for the BIOS-low-level-formatting-routine:

Q) 3.9  Do I need a reference disk for my SCSI drive?

No, only for the controller.  This question has come up a lot lately.  If
 you
are having problems getting a new drive to work with a existing working S
CSI
setup, call the drive manufacturer and try not to tell them it is a PS/2.
 
Also refer to some of the earlier SCSI questions about problems that aris
e
(switching drives around works many times).  Most tech support people hav
e
heard rumors that PS/2's need reference disks for everything and that the
y are
incompatible with everything.  So they either tell you to get the referen
ce
disk (usually from IBM as if they support third parties ever) or that the
ir
drive is not compatible with PS/2 computers.  I would also call the SCSI
adapter manufacturer (assuming they are still around and supporting it) f
or
clues.  Remember setting up SCSI drives can have a lot of variables, keep

checking for proper ID, proper termination, and the like.

When shopping for a SCSI controller card, I would recommend either the Ad
aptec
1640 or the Future Domain MCS-700 (or the MCS-600 which is the same excep
t
uses an Apple type DB-25 external SCSI connector instead of the standard 
50
pin.  Both use the 50 pin connector for the internal drives).


Q) 3.10  What is a 16550UART and do I need one? Does my PS/2 have it?

The 16550 is a UART with two 16 byte FIFOs.  A UART is the part of a seri
al
port that takes byte-wide (characters) data and converts it to bit-wide
(serial) data, and visa versa.  The FIFO is a buffer which can hold chara
cters
until the CPU is ready to remove it or until the serial line is ready to
transmit it.  The 'normal' UART in the PC (the 8250 or 16450) only has 1-
byte
FIFOs.  The additional 15 bytes can be useful when the CPU is busy doing 
other
things - if the CPU isn't able to remove data fast enough, it will be los
t.
The OS or program has to explicitly support 16550 to make full use of its
advantages.

A very important thing to note is that under DOS, the CPU doesn't have
anything else to do, so the 16550 is wasted.  Only under multitasking
operating systems does it really become useful.  The 16550 will *not* mak
e
your file transfers any faster, it will only prevent data from being lost
 and
relieve your CPU of some overhead.  If you notice system performance drop
ping
like a rock when file transfers are occurring, a 16550 may be helpful.  I
f
you see re-transmissions (bad packets) or "FIFO overrun's" during file
transfers under a multitasking OS, try the same thing under DOS - if the
errors go away, then chances are a 16550 will be useful.  If they remain,
 then
your problem is likely to be elsewhere.

PS/2s without the more modern 16550A UART are usually limited to lower da
ta
rates (not because of the 16550 UART but because the other UARTs are slow
).
Usually 14.4k max with no compression.  The PS/2 models and type of UART 
are
listed below.

From: Aron Eisenpress :
The following information is taken directly from the PS/2 Hardware
Interface Technical References.

Four types of serial port controllers have been used on the system
boards of PS/2's.

To programs, the Type 1 controller appears to be identical to the serial 
port
on the IBM Personal Computer AT IBM Personal Computer Serial/Parallel
Adapter.

The Type 2 controller incorporates all functions of the Type 1 and also
provides support of the first-in-first-out (FIFO) mode.

The Type 3 controller incorporates all functions of the Type 2 controller
 and
provides the Direct Memory Access (DMA) mode.

The Type 4 controller incorporates all the functions of the Type 3 contro
ller
and provides additional I/O addresses.

For type 1 and type 2 controllers data speed should not exceed 19.2kbaud.
Type 3 and type 4 controllers support up to 345.6 Kbaud.

Below is a list of the type of serial controller used in each model in th
e
Micro Channel PS/2 line:  (Note, these are IBM's published times.  I have
 been
advised by
Mark Seecof  that any PS/2 with the 16550A (including the

16550AF) is
capable of over 19.2 Kbaud as long as the software supports it).

           8550                    1,2                19.2 Kbaud
           8551 (N51)              2                  19.2 Kbaud
           8554 (CL57)             2                  19.2 Kbaud

           8570                    2                  19.2 Kbaud
           8573 (P70)              2                  19.2 Kbaud
           8580                    1,2                19.2 Kbaud
           8590                    3                 345.6 Kbaud
           8595                    3                 345.6 Kbaud

IBM uses a proprietary chip instead of the 16550 UART in PS/2's.  The ser
ial
port controller in all of the above PS/2 models (except the PS/2  models 
55
and 65) is compatible with the National Semiconductor NS16450 serial port.
The serial port controller in the PS/2 models 55 and 65 is generally
compatible with the NS16550A serial-communications controller.

PS/2's with Type 2, Type 3, or Type 4 serial port controllers support the

first-in-first-out (FIFO) mode.  The exception is the PS/2 model 50 with 
a
Type 2 serial port controller.  According to the PS/2 Hardware Interface
Technical Reference - System Specific Information, model 60's and 80's wi
th
Type 2 serial port controllers do support FIFO mode.

Q) 3.11  Should I buy an internal or external modem?

In general, it is better to go with an external modem for two reasons.  F
irst
MCA slots are valuable commodities in most systems (i.e. Model 50s with o
nly 3
slots) and secondly, an MCA card modem will be a lot more money when a
standard external modem will work fine.  Also an external modem provides
visual clues to tell you what is going on with the data.

Sometimes internal is the only way to go though.  The Windsurfer Adapter
with its 14.4k data modem, 9600 FAX and telephone answering/voice mail is
only available internally, however, this is not such a waste of a MCA slo
t
as you are getting several products on one card.  I believe in its last
incarnation (it has been discountinued) some versions were 33.6k capable 
which
is still ok for many.


Q) 3.12  What kinds of sound cards are available?

There are a few believe it or not.  Though new they cost around $150 whic
h is
a little steep these days for a sound card with SoundBlasters selling for
 $30.
Kahlon computers at www.kahlon.com and 800-317-9989 offers one for $125
(though I am not sure who actually makes it).  The original was the
SoundBlaster MCV which is an 8 bit card and probably should be avoided du
e to
the problems it has with compatibility.  The SoundBlaster Pro MCV is a 8 
bit
card which supposedly works better, yet both SoundBlasters are no longer 
made.
 The next option is the Audiovation/A ($249) which is a 16 bit card capab
le of
44.1KHz sampling rates is SoundBlaster compatible and is currently being
revised for better support.  Another option is the M-Audio Capture/A whic
h is
said to be more of a sound editor than one for games.  Another option is 
the
WindSurfer Card.  This is probably overkill as solely a soundcard for its
 $400
low price, but it does offer a 14.4k modem (some up to 33.6k), 9600 FAX a
nd
telephone answering/voice mail on one card. This card is probably not as
compatible as the Audiovation is, but maybe worth a test to see if it doe
s
what you would like.  The Chipchat is currently available in both 16 bit
($129) and 32 bit ($159 with wavetable)go to www.chipchat.com or call the
m at
(313)565-4000.  Reply Technologies has a card out using the chipset from
Creative Labs, the Vibra 16, which is SoundBlaster 16 compatible and it i
s
also available linked up to a Future Domain SCSI-2 controller.  One more
option comes from Piper Research at www.piper-research.com  and 612-459-2
770,
this is a SoundBlaster compatible card.  They used to only make a 16 bit 
card
($129.95), but now they have a 32 bit version ($159.95) and a 32 bit with
 3D
sound ($179.95).

  SoundPiper 32 as it cannot be bought separately.

The SoundBlaster and Piper Cards are industry standards and thus offer th
e
most compatibility in most games Piper uses the SoundBlaster Pro Chip fro
m
ESS.  Most these cards may cause problems in the Windows environment as t
hey
were developed before Windows was around, however for DOS games the
SoundBlaster Pro is THE card to have.  The Audiovation/A and the others o
nly
emulate a SoundBlaster using Mwave technology which is THE thing for WIND
OWS.
So depending on what you do most choose a card, also two cards can be use
d if
the reference disk is patched.

From thedean@ibm.net:
There has been much discussion regarding PS/2 Micro Channel - MCA - sound

cards. Here is a quick comparison.  This comparison addresses both hardwa
re 
and driver capabilities.  It is important to consider both, since if ther
e is
no driver to support a hardware capability then the capability is not use
able.

A perfect example is OS/2 drivers.  Although each sound card in this
comparison  has "16 bit" record/playback hardware, some cards use the
"SoundBlaster Pro MCV" driver shipped with OS/2 Warp.  This driver only
supports "8 bit", not allowing "16 bit" files to be recorded or played.

Q) 3.13 Can I run both a SoundBlaster and the Audiovation/A?

[Jacques@cpmc.ucl.ac.be (Alain Jacques)]
Yes, it works ... after patching the ADF file. What's conflicting is the
addresses of the game port, defined in both ADF's as fixed resources and
therefore the conflict cannot be managed by the POS itself. If you choose
 to
keep the game port on the SBPro, just as I did, your Audiovation ADF file
@8FD6.ADF should look like the end of this message.

If you have difficulties, don't hesitate to email to me.  BTW, there are 
new
Audiovation Windows drivers on IBM PC Co BBS (i.e. version 2.1 3D av211.
dsk,
av212.dsk, av213.dsk, av21util.dsk).

See Appendix C for Program listing.


Q) 3.14  Can I fake a keyboard so my computer will boot without it?

Well unlike the standard IBMs and clones, PS/2s perform a keyboard test a
t
boot.  Some have the option of canceling the keyboard test through a sett
ing
in the reference disk.  If you do not have this option you must leave the

keyboard attached (or if you have the engineering experience doctor up a
small board that sends the proper reponses to the test back and can plug
into the keyboard port :)).

Or use this device below reported by Louis Ohland 

http://www.raritan.com/newsite/guardian.htm.

Picture is at http://www.raritan.com/newsite/images/pgrdian.gif.

Blurb:
Each Guardian for PC, Mac, and Sun computers plugs into the keyboard port
and mouse port, and appears to the computer as its physical keyboard and
mouse. Since Guardian behaves like a keyboard and mouse, the computer wil
l
boot and run flawlessly.

Guardian is powered by the computer and provides ports so you can "hot"
connect a keyboard and mouse anytime to operate the system. Using Guardia
n
with PCs connected to a mechanical A/B switch will eliminate PC booting
and keyboard locking problems.

With Guardian in line, you can hot connect or disconnect MasterConsole
cable or a physical keyboard and mouse. For mission-critical servers
connected to Raritan's MasterConsole, Guardian provides a "fail-safe"
service port.

Guardian for Mac and Guardian for Sun also convert the keyboard, mouse, a
nd
video signals to PS/2 and VGA standards. This enables any number of Mac o
r
Sun computers equipped with Guardian, as well as PCs, to be connected to
MasterConsole and controlled with a single PS/2 keyboard, PS/2 mouse, and

VGA monitor.

S) 4.0 Upgrading Processor/Coprocessor/Disks/Video/CDROM

Q) 4.1  I don't have the money for a new computer or motherboard, what ca
n I
         do?

[PC Magazine 11-08-94, alkemyst@shadow.net)

Kingston Technology makes upgrades to raise the level of all chips (i.e. 
286
to 386, 386 to 486, 486 to 586).  Some are CPU replacements, others are
daughterboard cards, and the granddaddy is the MCMaster.  The CPU replace
ments
offer very little performance gain if your system is strapped with slow
peripherals and memory, but can get you running 386 or 486 software.  The

daughterboard 486/NOW! replaces both the CPU and math coprocessor, but
performance-wise it is a disappointment.  The MCMaster is MCA architectur
e in
action.  Using busmastering it allows the card to take over CPU functions
 and
make the computer run a lot faster using its own 128k L2 cache and up to 
32MB
of memory.  This card shows promise and in most cases performs better tha
n the
daughterboards and CPU plug-ins, however it lags slightly in DOS video
performance and video in general as it must 'cross' the bus on to the
motherboard.  Still the MCMaster is probably the fastest in this list and
 the
only upgrade that can add L2 cache to computers without the option.  [For
mats:
 486/NOW!:  models 70/80 to 33PD3 or 33PS3 (don't know what
the PD3 or PS3 maybe D3DDX and S3DSX.); MCMaster:  for models 55, 56, 5
7, 65,
70, and 80:  to 33MHz or 50MHz...note only 50MHz with 8MB+ boosted perfor
mance
and so it did significantly.  The price for this level is $1000-1400.][ND
P:
built in to the 486 chip.]

Intel has a SnapIn 386 module for PS/2 models 50, 50Z and 60. It features
 a
20MHz 80386SX, 16K cache and it can utilize an existing 80287 math
coprocessor. I have one in a model 60 and have had no problems with it.

IBM offers for the 386 PS/2 Model 70 and 80 with 16 or 20MHz processors a

Power Platform upgrade with a 486DX33 on it.  See above IBM PARTS LIST fo
r
features and part numbers.  These are expensive ($500-700) and are no lon
ger
made, but can still be obtained esp. from the Boulder Parts Surplus Plant

800-388-7080.

IBM re-released the Blue Lightning chip for PS/2's again.  This time it i
s for
the 25MHz machines also.  It offers 16K internal cache, enhanced 386/486
instruction set, and 33/66MHz performance (though the 33 will be replaced
 with
whatever your system runs at).  Also you can add a math
coprocessor.  The L1 cache design is supposed to be what sets this chip o
ff
from the rest (Hypertec).  I talked to a IBM tech who actually had the Cy
rix
DRx2-50 and was asked to help test out this new chip.  He stated he saw t
he
same performance jump from going to a Cx486DRx2-50 from his 386DX25 as go
ing
to the BL2 from the Cyrix.  I would call that an upgrade worth considerin
g,
esp. at the mere $345 IBM is asking.  IBMPN#13H6698 $345.

IBM also has a SLC2-66 chip out for 55SX offering up to 10x the
performance.  Features 16K L1 cache, enhanced instruction set, and allows
existing 387SX usage providing it is a 33MHz chip. IBMPN#13H6694 $259.

Cyrix offers very good options for the 386 to 486 conversion if you are o
n
a tight budget.  Their DRx2 line offers clock doubled performance at a lo
w
price.  The chips perform very well and just require removal of the 386 a
nd
popping in the new chip.  Pricewise they can't be beat and though not off
ering
the performance of their $500+ cousins they come close enough for most pe
ople
at half the cost or more (This is due to their tiny 1k L.1 caches). [Form
ats:
386 to 486 only:  DX16MHz to 16/32MHZ, DX20MHz to 20/40MHz, 25MHz to
25/50MHz, DX33MHz to 33/66MHz, none for 40MHz yet.  DX16MHz and 20MHz sys
tems
can use the 25MHz chip if available.  Some versions for SX models.][NDP: 
 387,
Cyrix 83D87 rec.]

Evergreen's Rev to DX4 and 486 chips are more expensive and generally fas
ter
than most others at a lower prices.  One problem is compatibility, many
computers can not run at the clock tripled and quadrupled rates and must
fall back to clock doubled rate negating the extra cost of the upgrade.
Another note is the processor board cards will not work with all systems 
due
to space constraints, it is best to measure and make sure you got at leas
t 1"
or more room above the processor and can afford to give up peripheral car
d
space if it is in the way.  A processor card may be worth it if it works 
due
to the fact of a larger L1 cache and the usage of an IBM Blue Lightning C
PU
in some formats.  [Formats:  386 to 486: DX16/DX20MHz to TI 486SXL2 or Bl
ue
Lightning 16/48 or 20/60, DX25MHz to TI 486SXL2 or Blue Lightning 25/75,
DX33MHz to Blue Lightning 33/66 or 33/99; 486 to 486:  SX/DX25MHz to 25/7
5MHz,
SX/DX33MHz to 33/99MHz, SX/DX50MHz to 50/100MHz.  Note the DX4 only clock

triples or doubles not quadruples like a DX4 seems it should.][NDP: vario
us.]

H.Co is offering many chips now from 286 to 486 all the way to a 386 to
DX4/100.  I am interested to see how these perform as I have no info othe
r
than formats available.  [Formats:  286 to 486:  6-16MHz to IBM50MHz; 386
to 486:  SX/DX16/20MHz to TI40MHz, DX25MHz to TI50MHz, DX25MHz to IBM50MH
z,
SX/DX33MHz to IBM66MHz, SX16MHz to IBM48MHz, SX20MHz to IBM60MHz, DX16/20
MHz
to IBM 60MHz, DX25MHz to IBM75MHz, DX33 to IBM99MHz; 486 to 486: 25MHz to
75MHz, 33MHz to 100MHz, 40MHz to 100MHz.][NDP:  ?]

A small company called MicroModules System also offers CPU upgrades.  The
y
are at 10500-A Ridgeview Court, Cupertino, CA  95014-0736.  408-864-7437.
Then there are AOX Inc.'s MicroMASTER busmaster boards. From 386-20 to
486/33 with up to 8MB of RAM on board. This is what the Kingston is now.
Kingston bought the rights to manufacture the MicroMaster.  The early 286
to 386 versions can utilize 132PGA chips and usually 486DLC and DRx2 chip
s
will work, but these are no longer made and must be found used or in surp
lus
warehouses.  [Formats:  286 to 386:  to 20MHz, 25MHz, 33Mhz][NDP:  387.]

In summary the MCMaster fully configured, i.e. 486/50 with 8 to 16MB of R
AM
offered the best performance, followed closely by Evergreen's DX4, Cyrix 
and
finally Kingston.  H.Co, IBM, Intel, and AOX were not tested.

Also note that adding 8MB of RAM will usually add as much performance as 
the
CPU upgrades do and add a lot more performance if combined with the CPU
upgrade.  The addition of RAM, a Video card, faster hard drive, and a new
 CPU
will make the most improvement and if done over a period of time makes se
nse,
however if these are going to be bought 'lump sum' it is probably better 
to
buy a 486 clone if you are looking for speed.  If reliability is a big fa
ctor
and speed not as important as being able to run the new 386+ software the
n
with PS/2's usually there are no problems as there are with most clones.

Update as of 10/28/98, there are no processor cards (AOX MicroMaster or
MCMaster) available for the PS/2's anymore.  Evergreen and Kingston are s
till
selling their processor upgrades and prices have fallen dramatically.  Fo
r the
486/33 systems you can get the AMD 586/133 (equivalent to a Pentium 75) f
or
about $70 from CompUSA, Fry's, or Circuit City (list is about $129 for
Evergreen's and $99 for Kingston).


Q) 4.2  What are the Benchmarks for these Processor Upgrades?

Benchmarks are meaningless to give as it would not be the same machine no
r
the same variables but below are some 'averages'.  Benchmarks are only go
od
to compare the same settings to the same settings so if you have a machin
e
listed and have different marks don't post to USENET asking why, as it is
simply because you have a different configuration.  The basic outline
discussed above gives you the breakdown in percent a CPU upgrade is worth
36-134%, a daugtherboard is worth 137-681%(681% percent seems high and wa
s
not supported by PC Magazine's data. The 137% seems more real world as th
ese
are very close to direct CPU replacements for the most part), and an MCA
processor card 263% which offered the largest increase, but at a very hig
h
cost.

Also note that a 486 is just an enhanced 386 with L1 cache.  This L1 cach
e
is responsible for up to a 500% performance increase.  L2 caches can offe
r at
most a 50% performance increase.  Try disabling all caching on a 33MHz 48
6 and
compare the marks to a 33MHz 386 you will be surprised how close they are.

Winstones are the most quoted benchmark today, so a table of average Wins
tones
was computed.  Keep in mind that this benchmark is a benchmark which rate
s the
execution of certain popular sequences, scripts, in about ten or so of th
e
most popular window programs.  With this in mind this should give a *very
*
real world figure.  Also keep in mind that when the processor upgrades we
re
done, the systems below remained stock which is very crippling especially
 with
a 486 trying to pull files from a 20ms access hard drive.

The processor quoted benchmarks came from a database of at least 50 diffe
rent
platforms each for the 25, 33, 2/50, 2/66 with the 33 and 66 MHz numbers 
being
taken as an average of no less than 50 machines for each.  This should gi
ve a
good average number as there was no price range or brand criteria only wh
at
was available to the home user (i.e. no FCC class A or non-FCC tested
dynamos).

The 50MHz numbers were for 5 tested machines.  The AM40, CxS40, and SLC2
numbers are for two or less machines each and may be bad examples of the
capability of the chips being either superior or inferior to average numb
ers.
The Pentium numbers came from an average by PC Magazine and should be a g
ood
average figure.

s
                                          slams against them in general.


Q) 4.3  Which Math Co-Processor should I use?

For 286 systems a 287, 386 systems a 387 and for processor upgrades usual
ly
the same unless they perform NDP functions on chip.  It may be wise to
purchase an enhanced NDP, such as the 83D87 from Cyrix which is much fast
er
(5-15% in applications, up to 20% on certain benchmarks) than the Intel p
art.


Q) 4.4  How can get rid of my slow stock Hard Drive and get a faster and
        larger capacity version?

PS/2's are notorious for slow, low capacity hard drives.  The Model 50's
20MB drive has 80ms access!  The easiest way to go is to add a SCSI or ES
DI
card.  SCSI in general offers better performance, the ability to add up t
o 7
peripherals and easy to find drives.  ESDI offers more UNIX compatibility
(though with new drivers this will change) and was stock on some PS/2's,
most now use SCSI.  If you have SCSI or ESDI already you can add at least
 one
more drive no problem.  It is a bad idea in general to try and replace th
e
MFM type ST-506 drives on early PS/2s as buying a SCSI card and new hard 
drive
is a cheaper, faster and more reliable solution.

Keep in mind that if you add a SCSI drive and controller make sure the
controller has boot ability in the BIOS or else you will have to boot off
 of
the original PS/2 drive.


Q) 4.5  How can I add a second floppy drive and what type will work with 
my
        PS/2?

Kits for mounting these drives can be obtained from PS Solutions 214-783-
6997.
They sell high quality, complete kits for almost every possible internal 
drive
mounting option.

3.5" internal for:
     25/30, 50Z/70, 50(front bay 50Z/70)
     60/65/80         (via a 5.25" internal mount and allow for two half-
high
                       3.5"/5.25" mounts)

3.5" 'H'-skid type for:
     35/40/56/57/76/77(via the 5.25" int. option)
  
5.25" internal for: 
     35/40/56/57/76/77(all with 3.5" mount options available)
     60/65/80         (vertical mount, also with dual half-high 3.5"/5.25
"
                       options)
     90               (for removable media in the 5.25" bay w/ 3.5"HD opt
.)
     85/95            (for removable media and rails for fixed media)

For systems with 'slide-it-right-in' options the necessary bezels can be
obtained from DakTech 800-325-3238 very cheaply for a high quality produc
t.
(Also for bezels with missing clear plastic 'windows' which make it hard 
to
see the drive lights.)

First, we will discuss the 3.5" addition as it is a more common event. 

The first thing you need to do is to determine the MB capacity of what yo

want to add.  There is 720K/1.44MB/2.88MB and they can all read/write at 
their
level or lower (i.e. a 2.88MB can read/write 1.44MB and 720K).  Not all
systems can use all 3.5" drives.  [I would like to include a list of whic
h
systems CAN'T use the 1.44MB drives and which systems CAN use the 2.88MB
drive].  After determining what you need/want to add you can start the
installation.

*ADDING A 720K DRIVE:

*INTERNAL OPTION:
*EXTERNAL OPTION:


ADDING A 1.44MB DRIVE:

INTERNAL OPTION:
There are two types of 1.44MB drives and though they do the same thing th
ey
are not interchangeable on the internal level.  One has the disk light ab
ove
the media slot and the other has it below the media slot (there are other
 ways
to tell but this is the easiest method).  Once you determine this it is s
imply
a matter of either popping off the faceplate bezel blank sliding in the d
isk
drive until it 'clicks' and popping on the new bezel.  Sometimes the exte
rnal
case needs to be opened like a model 50 for example, but then the procedu
re is
the same.

*EXTERNAL OPTION:


*ADDING A 2.88MB DRIVE:

*INTERNAL OPTIONS:
*EXTERNAL OPTIONS:

Now we will discuss the addition of a 1.2MB 5.25" drive.

These can be both adding internally or externally.  External is the commo
n way
as most PS/2s do not provide a 5.25" floppy bay and those that do usually
require a vertical mounting arrangement.

*The models supporting a direct 5.25" mount internally are:

All other's need to either buy the kits listed above or need to use an
external mounting option.

*INTERNAL MOUNTING:
*The internal 5.25" drive is installed by sliding it into the bay
 [someone please contact me with the directions for the direct installs
..do they click into place like the 3.5" drives or do they require
screws/or combination.]

The kit-type installations are completed by following the manufacturers
guidelines for the kit then going to the drive hookup section below.

*Hooking up the drive to the drive card:

EXTERNAL MOUNTING:

Find a place on you desk or area where the likelihood of the drive being
knocked down is low.  Then set the drive down and detach the cable if pos
sible
from the drive to prevent it being dragged around in the installation
procedures.

Now you are ready to set it up:

IBM:
Open the case of the computer, find an empty MCA slot. Plug in the floppy
controller card and run the cable to it.  Now close up the computer and p
lug
in the 5.25" external drive and you should be all set.

Cristie drive (available only in the UK?):
The drive connects to the B-3.5" floppy connector. The cable then goes in
side
the computer, through the slot in the back and finally to the drive.
It doesn't actually use a slot, but looks neater than having a cable run 
out
the front B: drive bay to the 5.25" drive.

Radio Shack/Tandy's 5.25":
This drive will give you 360 and 1.2mb formats via the parallel port, and
allows you to plug your printer in too -- so you lose neither a drive bay
, an
expansion slot, or much money. The drive can be temperamental, usually
requiring a print job before the drive is acknowledged (maybe initializat
ion
of the parallel port is what is required). The print job can be empty als
o.
This drive is an ideal solution which lets you keep your tape backup and
expansion cards in place, even if requiring an extra step to use the driv
e.

Sysgen unit:
Its not a very awkward installation.  Just pop off the cover. Unplug the
floppy connector.   Snap a small board in on supplied post, and re-instal
l
the floppy connector and route the other out the box to the external unit.
It works as drive B in 1.2 meg mode.  The IBM's I saw mapped above the la
st
hard drive, so that floppy came in as D or E. Works fine with SCO Xenix t
oo.

[I have been informed that the IBM drives also require the usage of one o
f the
3.5" floppy bays for a second drive card, is this the case for all 5 1/4"
drives?]


Q) 4.6  Is there a SVGA option for my PS/2?

There's XGA and XGA/2 from IBM and the Reply Video Adapter from Reply
Technologies. Both of these have 1MB of unexpandable VRAM and can display
 256
colors at 1024x768 non-interlaced and go to 1280x1024x16.  The IBM card u
ses a
IBM chip and the Reply the Cirrus Logic CD-GL 5426 chipset which is VESA
compatible.

IBM also has a SVGA card for servers.  As such, it maxes out at 256 color
s.

A note about XGA/2, it is not VESA compatible at the hardware level...the
re
are drivers that allow it to be VESA compliant but these drivers freak ou
t
many pieces of commercial software...be advised.

Also on the high end, I know of Matrox making some in the $1k + range tha
t
have 1MB+ of VRAM but I have yet to hear of the performance or to run int
o
someone who has purchased one.  Also RasterOps Colorboard 1024MC can disp
lay
1024x768x16.7M (no modes above 1024x768) with the 3MB of VRAM it has, but
 it
is slow compared to other video cards and expensive. Also I am curious as
 to
the specs of the IBM Image I Adapter which is about $2.7k with 3MB VRAM f
or
1280x1024x256 color support.

ATI has the Ultra Pro 2MB a 2MB VRAM card with a 32 bit accelerator.  Thi
s
card had be found for as low as $250 (retails for ~$500)[prices as of 199
6]. 
I am curious to its performance as the 64 bit versions are top in their c
lass,
but for just the ability to get greater color depth the 2MB card is worth
 it. 
Be advised that ATI has the habit of constantly changing its drivers so
compatibility issues may arise and a downtime for new drivers may be upon
 you.
 It uses the Mach32 chipset so is widely supported, NT 4.0 supports this 
also.


Q) 4.7  How can I add a CD-ROM drive to my PS/2?

Most of the time an external CD-ROM can be added if you have a SCSI card 
with
no problem.  Internal CD-ROMs can be added to any PS/2 with a 5 1/4" bay,
 some
that have internal 5 1/4" bays (60/65SX/80) can use special bezels to
vertically mount a CD-ROM.  In these cases caddy-type drive are mandatory.
The drivers needed are usually dependant on which SCSI card you use so co
ntact
the manufacturer if CD drivers were not supplied.


Q) 4.8  How can I build a Multimedia PS/2?

You can build a multimedia PS/2 the same way as a normal PC.  The excepti
ons
are sound cards.  As it stands now you must use the SB-pro or clone for D
OS
and the Audiovation/A or equivalent for windows.  Any SCSI CD-ROM should
work with a SCSI card and any big monitor will work.  Reply Technologies,
Matrox, and ATI all make video cards for SVGA, some have up to 3MB of RAM.
Also any speaker setup will work with the soundcards providing they have
they same connectors (usu. RCA or mini RCA).  Other than that you will
want a fast hard drive and probably a 33MHz or faster machine.

Here is an example:

PS/2 Model 80-A21
Cyrix Cx486DRx2-50 Processor upgrade with 33D87 NDP.
Mag DX15F Monitor
Reply Technology Video Adapter
Plextor 4x CD-ROM (internal mounted)
Piper or ChipChat SB-Pro sound card
Audiovation/A sound card
Seagate ST-3600N SCSI hard drive
Future Domain MCS-600 SCSI controller.
Sony Speakers
CH Game Card III
Generic PC joystick


Q) 4.9  How can I get sound effects in DOOM?

[From: cousinad@aol.com (Cousin AD)]

Option #1:
Choose all the WRONG settings for the DMA, IRQ and I/O address.  Save
settings and play...  You may still need to re-boot one time before this
works.

Option #2:
Choose the wrong setting for the I/O Address (use the correct settings fo
r
the IRQ & DMA).

The above worked for me, but I found problems setting-up for modem play...
 I figured, hey, you can't have it all...  Then I got another suggestion
that really solved the problem...

Option #3:
Choose all the CORRECT settings for the DMA, IRQ and I/O Address.  Exit
set-up and choose yes to "Save settings before exit."  Then, before
starting DOOM, open the file DEFAULT.CFG in an ASCII text editor (MS-DOS
"EDIT" for instance).  Change the "SND_SBPORT" line from 544 to 220 or
240, depending on your SoundBlaster MCV configuration.  Save the
DEFAULT.CFG file and start DOOM...

Q) 4.10  How can I make my PS/2 Model 90/95 a Pentium 180/200MMX machine?

First it is going to always be a P180MMX as the clock tripling runs at 3x
60
and
there is no easy way to modify this, although if a budding Electrical
Engineering
student wants to do so I am sure the list would love a P233MMX version. A
s
long
as the chip is above the rated speed you are OK, just like it made sense 
to
always buy the 33MHz 387 math coprocessor as you could use it in any 387 
slot
and not have to repurchase a FPU when you upgraded CPU's.

Secondly, you must use the Overdrive version of the P180MMX or P200MMX as
 the
non-Overdrive version do not work properly in this capacity.

Also note the P90 version of the Type 4 complex is needed.  Contrary to
popular
belief all of the Type 4 complexes are as different from each other as th
ey
are
to the Type 1, 2, and 3 complexes (as well as each different kind of thos
e).

You need the "Y" upgrade of the Type 4 complex, announced Oct 1994, and k
nown
as
IBM Part Number/FRU#  06H3739 or 19H1027 (and a few other crossreferenced

numbers).
These go for about as much as a small third world country (or half the
continental
United States if purchased directly from IBM).  So make sure you can affo
rd to
lose
this board should any of the below modifications screw up your processor 
board
or
PC.  If performed as outlined and no mistakes are made it is a totally
reliable
modification and brings your machine to the front of the pack.  Remember 
most
applications peak out at 200-233MHz Pentium speeds and the PII's are real
ly
only
useful for games, high-end graphics, and high-end multiuser server
applications.

Disclaimer

Modifying your processor complex with these instructions will void your
warranty
and may cause irreparable damage resulting in a non-functioning processor

complex
if performed incorrectly. There are no warranties expressed or implied. M
odify

 was
usually three years depending on country of purchase. Check your warranty

Introduction

The following instructions can assist you in modifying the 90Mhz Pentium
processor
complex that was originally manufactured in the IBM PC Server 500 System3
90 so
that you can use the PentiumAE Overdrive 180Mhz with MMX chip. If you un
plug
the
PentiumAE 90Mhz chip from the complex and plug in the 180Mhz PentiumAE 
Overdrive

without this modification, you will experience two problems:

I. The electric fan that cools the PentiumAE Overdrive chip will not hav
e power

   to turn the blades. You will 'cook" (burn out) the PentiumAE Overdriv
e due
to
   inadequate cooling. (The 90Mhz PentiumAE chip uses a heat sink instea
d of an

   electric fan.)
2. Without providing 5 volts to the overdrive chip, the chip will run at 
about
   25Mhz which is slower than the installed 90Mhz chip.

Directions

* Locate and have a working reference diskette for the PC Server 500
available.
  You will need it if you use a different processor complex board than th
e one
  currently installed. You should not need it if you remove, modify, and
replace
  the same processor complex board that is currently installed. Better to

locate
  and have it ready than to not have it.
* The processor complex does not use a ZIF (zero insertion force) socket 
for
the
  PentiumAE processor. The old 90Mhz processor must be carefully removed
. (A
good
  quality jewler's screwdriver was useful to the author in starting to pr
y the
  chip from the socket and then working around the perimeter of the chip
  increasing in small increments. Insert the tip of the screwdriver betwe
en
the
  socket and the chip. Use only the socket surface and not other chips or

edges
  on the board as fulcrums for prying.)
* Solder an insulated wire from the +5 volt regulator to the two unused p
ins
on
  the PentiumAE 'internally no-connect'.
* The two pins are technically labeled AN01 and AN03. There are no labels

visible
  that say AN01 or AN03.
* After the wire has been soldered to all three points and allowed to coo
l,
  carefully align all pins of the new processor to their respective holes

taking
  note of the key (missing pin on one corner). Carefully push the new
processor
  into the holes. The new processor pins may be longer than those of the 
old
  processor and therefore there may be a gap between the bottom of the ne
w
  processor and the socket surface.
* Reinsert the processor complex into the PC Server and reconnect the sig
nal
wire.
  Power on the server and assure that the fan on the Pentium Overdrive
processor is
  turning (a flashlight aimed at the fan when power is applied will proba
bly
be
  necessary).
* You will note that the LED display on the front of the PC Server 500 wi
ll
say
  "60Mhz" instead of "90Mhz." This is normal.

Modify at your own risk! Modification will void warranty.
    

S) 5.0 Adding System and Cache Memory

Q) 5.1  How do I add memory to my PS/2 off the motherboard?

[Test from PC Magazine January 28, 1992]

There are several RAM cards out there for the PS/2 and you do not necessa
rily
need a 32 bit card to get the max performance as will be shown.
(all cards tested on a Model 70-A21).

KEY:

 %READ 3D The read speed of memory using 4K blocks in sequence from 0MB 
to 16MB
         in relation to motherboard memory writes.
%WRITE 3D The write speed of memory using 4K blocks in sequence from 1MB
 to
         16MB blocks in relation to motherboard memory writes. (not less 
than
         1MB due to that memory being of the resident OS)
TESTED 3D The as TESTED config, 8MB of 80ns RAM was used for each card.
   MAX 3D The maximum memory able to be put on the RAM card in MB.  Thou
gh MCA
         computers don't allow DMA or direct memory access transfers past
         16MB, certain OS's for non-DMA type usage i.e. disk caches and E
MS.
  SIMM 3D 9 bit (30 pin) or 36 bit (72 pin) SIMM requirements.
SOCKET 3D The amount of SIMM sockets on the RAM card.
256-16 3D The size of SIMM it can take in K or MB.
INTEGR 3D The integration of the card to the system.  BIOS is the right 
way
         and allows all memory to be read at or during POST.  T0 is Track
 0
         method which is not as per IBM spec. This uses a special driver 
from
         the hard drive before the OS loads and thus is not usually cache
d
         and is reflected below in slower speeds.  BOTH of course means b
oth
         can be used (on the CuRAM if BIOS is used 16MB is max and if T0 
is
         used then 32MB is possible).  T0 also has the problem of not bei
ng
         tested by the system.  Unless the card does this any memory erro
rs
         do not get mapped out.
  POST 3D Whether or not the memory is shown on the screen at POST.  All
 BIOS
         type card 'POST' their memory, but some do not show it.
BKFILL 3D Whether the RAM card allows backfill of any deficiencies of th
e 640k
         base system RAM, more useful in 1MB systems and can allow 0
         wait access through the MCA channel and increase performance on
         such systems by 50%.
 PORTS 3D Either (P)arallel or (S)erial included or as an (o)ption. PS m
eans
         one parallel and one serial included, PPSo means there is an opt
ion
         for 2 parallel and 1 serial port and so on.  NONE means no ports
 are
         provided or offered as an option.
MODELS 3D The supported models, A 3D Models 50-65SX, B 3D Models 70-80
 and C 3D
         Models 90-95.  Note if BC is specified it means a 32 bit card.  
Cards
         with only a B designation do not work with 50-65SX or for some
         reason the Model 90-95 even though it was a 32 bit card.

The winner here was the MicroRAM SC (a 16 bit card).  Both cheap and with
 many
memory options.  The 386 version offers a parallel and dual serial option
 that
would be a wise purchase if you needed those but the 9 bit memory it uses

needs to be installed in banks of four and thus in general the SC is the
preferred solution offering 100% of the performance of its 32 bit brother
 in a
16 bit config. (note:  I don't know if the 16 bit cards will work as well
 with
processor upgrades, but clearly they worked as well in the 386/25MHz syst
em
and were recommended for the 486 90/95.)

Please note that the 16 bit cards scored just as well in most cases and a
re
less money.  Any card the scored percents of 80/71 operated at 0 wait sta
tes.
The MicroRAM allows 1 wait state with 120ns and matched memory with 100ns
,
it will operate at 0 wait states with 85ns memory (this was not tested in
this test and is purely from the manufacturers mouth).

As of 1998, ChipChat (313)565-4000 (www.chipchat.com) now sells the Micro
Ram
SC cards.  They have been changed a bit though I think as they no longer 
work
on the Model 90 or 95.  They use four 36 bit 72 pin 80ns parity SIMMs in 
any
combination of 1, 2, 4 or 8MB chips, are compatible with models 55, 57, 7
0,
P70, P75, 77 and 80, but not the 90 or 95.  They are 32 bit cards, but ca
n
also be used in a 16 bit slot.  They are also compatible with Win 95 and 
NT.


Q) 5.2  How do I add cache memory to my PS/2?

You can't unless it comes already on the board or you purchase a CPU upgr
ade
card with cache built in.

From Louis Ohland :

Type 1 complexes have a socket to add 256K L2 cache.  This can be had for
 $25
from NSI at www.wwtrading.com/ps2.htm.


Q) 5.3  Can I use 4MB modules if IBM only calls for 2MB?

Supposedly you can, but not per IBM.  I had both a 80/20MHz and 80/25MHz 
here
recently with both 4MB and 2MB modules, but forgot to test this when I ha
d
the chance.  I don't want to say you definitely can until I or someone I 
trust
has done so.  Until then by the memory at your own risk, it may very well

work, but give data dropout at times.


Q) 5.4  Who has memory the cheapest?

Really depends on what memory you are looking for.  If it is SIMMs check
www.pricewatch.com, if it is for proprietary IBM memory you are better of
f
looking on comp.sys.ibm.ps2.hardware.


Q) 5.5  Is there a way to identify a PS/2 RAM card or SIMM?

[From Aron Eisenpress ]

If the SIMM slots are 3 on the left and 1 on the right then it is a 2-14.
  If
the slots are 2 and 2 then it is a 2-8mb adapter.  There was a recall abo
ut 4
years ago on 2-14mb adapters that had data integrity problems with 4mb SI
MMs,
but the problem was not ever produced outside the lab that was reported. 
 If
it is 2-14 and has a sticker then it is probably one of the problem adapt
ers.
However, the recall has expired and IBM is no longer providing replacemen
ts.


Q) 5.6  What is the ECC memory option on some of the newer PS/2s?


Q) 5.7  What cache size do I have/can I upgrade to?


S) 6.0 Diagnostics

Q) 6.1  What do the POST beeps mean?

Beep(s)                 Errant device
No beep                 Power supply, system board
1 short beep            System OK
2 short beeps           POST Error displayed on monitor
Repeating short beeps   Power supply, system board
3 long beeps            3270 keyboard card
1 long, 1 short beeps   System board
1 long, 2 short beeps   Display adapter (MDA, CGA)
1 long, 3 short beeps   EGA
Continuous beep         Power supply, system board


Q) 6.2  What do the POST codes mean?

Note if errors are encountered with the reference disk in the drive they 
will
be identified.

See Appendix D for full listing.


Q) 6.3  Why when my system boots fine sometimes the reference disk 
        diagnostics report errors?

This is usually a case of non-IBM components added to the system.  Some
examples are video adapters, hard drive controllers, and the like.  In mo
st
cases, POST is always right and the reference disk is tricked into thinki
ng
there is a problem so don't have a heart attack when it gives you the:
'Replace system board' message it could just be a normal option generated
error.  Also lock-ups are common with some video cards added to the syste
m.


Q) 6.4  How can I *REALLY* find out if these errors are just bogus?

The *EASY* method if your system hangs on the full tests is to enter -A
from the reference disk main menu and select the test it hung up on.  If
everything checks out then no problem.

If you want it to run the full test without hanging the only method is to
remove each card and reboot with the reference disk allow it to auto-conf
igure
and then reboot and run the reference disk tests.  If the system hangs no
w
then there is a problem with the system not related to added options, con
tact
IBM or a repair tech promptly and try not to use the machine until it is
looked at.


Q) 6.5  OK I got a problem, who can I get to fix it?

Solutronix [closed as of 10/28/98], 7255 Flying Cloud Dr., Eden Prairie, 
MN
55344; 800-875-2580.  In one example, they replaced the video driver chip
 and
several "likely to fail" chips.  The repair, including shipping, cost $29
5. 
All repairs are warranted for six months, even if it is not related to th
e
original fault.

Micro Exchange [closed as of 10/28/98], 682 Passaic Avenue, Nutley, NJ  0
7110,
(201)284-1200, FAX (201)284-1550.  They have always been very professiona
l in
all of our transactions.  They sell used/demo and some new parts as well 
as
doing repairs.  In February their rates for system board repairs were:

8570/20MHz  $145          8570/25MHz    $155         8573       $225
8580/16MHz  $160          8580/20MHz    $165         8580/25MHz $170
8590        $275          8595          $325

Their warranty and repair offering is very similar to Solutronix.

In early 1993 IBM introduced the Personal Systems Card Repair service [cl
osed
as of 10/28/98]. The number is 800-759-6995, and their address is:

IBM
Attn: PSCR
11400 Burnet Road
Austin, TX 78758-3493

They offer 24-hour and 5-day turn-around service (the difference in price
 is
about $50), and the repairs carry the typical IBM 1-year warranty.

Anyone know of a good repair facility???  They are all currently closed.


Q)  6.6  What are the wrap plugs the reference disk sometimes refers too?

In order to perform a total test of the ports (when running IBM diagnosti
cs)
you need to provide the incoming signals to the port via a wrap plug.  Th
e
constructions of each (serial and parallel) are listed below:


                     PARALLEL PORT WRAP PLUG

To construct this wrap plug use a DB25 male connector. Utilizing a minimu
m
of 30AWG wire make connections as listed below:

      pin   1  to  13

      pin   2  to  15

      pin  10  to  16

      pin  11  to  17

      pin  12  to  14
 
Then before running the diagnostics attach the DB25 to the parallel port.

                      SERIAL PORT WRAP PLUG

To construct this wrap plug use a standard RS232 DB25 female connector an
d
wire these pins together.  Also using a minimum of 30AWG wire.

Updated via Brian Lee (blee@fish.share.net) who read the IBM FAX page.

       pin  2  to   3

       pin  4  to   5

       pin  5  to   8

       pin  6  to  20
    
       pin 20  to  22

Then attach this to the serial port before running the diagnostics.
           
Please note I have not tested this on an actual PS/2, but this does work 
on
standard ports and PS/2s don't have any propriety-type pins on the serial
 or
parallel ports.  Can someone let me know if these are the right 'loops'?


S) 7.0 Misc

Q) 7.1  What is the pin out for ...?

This is my attempt to have every pinout on a PS/2 listed and named.  At w
orst
this will solve the problem of someone referring to a DB9 as 'The little 
port
with some holes in it and in a 'D' on its side shape' :).  And at best it
 will
provide the information to build cables yourself and hybridize certain ca
ble
sets.

See Appendix E for listing.


Q) 7.2  What is the special SCSI connector by IBM?

I have just bought a third-party SCSI cable for my PS/2, and it works.  I
t
allows you to connect the 60-pin PS/2 SCSI adapter external connection to
 any
device with a standard 50-pin Centronics connector. So, there are three
options for getting this type of connector. By the way, the PS/2 SCSI
connector is the same as the one on the RS6000.  Of course, the alternati
ve
to all this is to use an internal SCSI device, if possible. The IBM inter
nal
SCSI connections are the same as those found in internal SCSI devices (th
e
50-pin rectangular connector).


FIRST OPTION:

Buy the IBM cable from your IBM dealer.  The part number is 32G4143.  It 
will
cost about $49.


SECOND OPTION:

Buy a third-party cable. I bought mine from Storage Solutions [closed as 
of
10/28/98]. Their number is (203)325-0035. Mine cost $75 for a 5' cable.  

Storage Solutions call the IBM connector a  "60-pin compressed" connector

(though they are not really pins - it's really a kind of edge connector).
 
They also know what you're talking about if you just call it an RS6000 SC
SI
cable.

Inmac (1-800-323-6905) also sells them (see their UnixSelect catalog).  T
hey
call it a Mini-Centronics (60) connector.  They charge a bit more than St
orage
Solutions.

There are probably other suppliers.  The key piece of information is that
 it
is
the same connector as on RS6000 machines. The IBM connector is *not* a Mi
ni-
SCSI connector. Not all suppliers know this, and they will try to sell yo
u
Mini-SCSI (which has 50 pins and is smaller than the IBM connector).

THIRD SOLUTION:

Make your own.  The SCSI connector is available from AMP (1-800-522-6752 
or
1-800-526-5142 or (717)564-0100).  The AMP part number is 557025-6 (not t
o be
confused with the 557025-5, which is the same connector, but without
thumbscrews to hold it in the SCSI port).  AMP also calls it a CHAMP .050
Series III Plug Cable Connector.  I was unable to find any AMP dealers wh
o
could supply this. I had to get it straight from AMP. And it would have b
een
so complicated for them to supply one as a normal order that they sent me
 one
as a free sample.  In the end I didn't use it though.  It turned out to b
e
almost impossible to solder.  It is designed to have each of the tiny SCS
I
wires forced into a slot that automatically strips the cable.  You'd need
 a
special tool to do that.  By the way, I bought a cheap SCSI cable and cut
 one
end off, so that I wouldn't have to solder the other end as well.

From Louis Ohland :

What about the internal cable for the Fast/Wide SCSI? I'm getting
close to getting the flat, .025 pitch cable and the AMP HPDB68
786090-7,http://connect.amp.com/AMP/bin/AMP.
Connect?C3D1&M3DBYPN&PN3D786090-7&button.x3D71&button.y3D7

The biggest problem is finding the Molex mini-centronics (called
half-pitch) 71660, http://www.molex.com/product/micro/71660i.html

After two months, I have THREE coming....

Another thing is the 50 pin edgecard connector for the IBM
controller. Available from Dalco and Jameco...Dalco part 40720

Q) 7.3  Where are benchmark programs located. What do they mean?

Benchmarks programs are a good way to compare systems and even better to 
see
how changes to a system affect it, however, it is unreliably to compare
benchmarks to other benchmarks (even if the programs are the same) unless
 the
same environments are used.

A very good and pretty much the standard benchmark program is COMPTEST ve
rsion
2.59 is the latest on 10/94).  This is excellent to compare system to sys
tem
and describes how to set up the autoexec and config files to run the test

under.  This is the control variable and allows apples to be compared to
apples.  This is a public domain program and probably the best in its cla
ss.

Other standards are somewhat variable as to what they will rate your syst
em as
A LOT of hardware manufacturers (esp. video card) are setting up benchmar
k
'sniffers' on their hardware to give back excellent numbers to the common
types of benchmark tests.  I would like a list of benchmarks known to be
 sniffed' for and the hardware that does 'sniff'.  The best way to preven
t
this is to make new benchmark test constantly and not to buy the benchmar
k
programs whose creators share what the tests look for with the manufactur
ers
before they come out.  What happens is X-company is coming out with a new
benchmark program, then Hardware R Us requests the parameters of the test
ing
and figures out what to send back to the benchmarking software to get FAS
T
but REALISTIC marks.  Usually the benchmark company is affiliated with th
e
hardware company so both benefit.


S) 8.0 Operating Systems (OS)

Q)  8.1  Can I run UNIX on my PS/2? Which UNIX variety works?

According to C. Beauregard:

Currently, most of the common disk controllers are supported: IBM SCSI,
IBM ESDI, AHA-1640, Buslogic, Future Domain.  X Windows runs under XGA,
XGA-2, 8514, VGA, etc.  Network cards include 3c523, 3c529, assorted
WD/SMC, IBM Ethernet Adapter/A, and a few ethernet, Token ring, and :)
Arcnet.  Basically, it's running on almost all MCA machines in one form o
r
another including most PS/2s, NCRs, Apricot, and some other extremenly
weird configurations (An IBM P390 300Mhz Pentium Pro with 1Gb of RAM, for
example).

The 2.0.x kernel series is supported via patches available at glycerine.
As well, MCA support is now in the 2.1.x kernel (well, with a few bugs),
meaning MCA hardware will be fully supported in Linux 2.2, although
support from specific distributions will probably come a little slower.
The exception is Debian, which has had complete MCA support since 2.0.

There's also been some work done on NetBSD for MCA, and Bob Eager is
working on some other BSD support.  Linux, of course, is way ahead of the
game.


Q)  8.2  Why won't certain UNIXs run on my PS/2?

The only thing that stops anything type of program from running on a PS/2
that would normally run on any other machine with the same CPU/memory etc

are usually the device drivers.  In the case of UNIX more than likely it 
is
just a matter of obtaining the correct disk drivers.  If you have ESDI an
d
want to run LINUX there is a ESDI fix available.  If you have a SCSI that
 is
compatible with any of the supported drivers you are ok also. Currently
there is a large Linux/MCA following and Linux is by itself a great OS...
32 bit and totally stable. 

For questions on Linux/MCA go to:
http://glycerine.itsmm.uni.edu/mca.


Q)  8.3  What is better for the PS/2, MSDOS or PCDOS?

I would have to say it is a toss-up.  In one hand, PC-DOS supplies specia
l
programs that are optimized for/unique to the PS/2 and may be helpful, bu
t
then
you have the problem that something may not be compatible with the MS-DOS
standard.  By purchasing MS-DOS, you may not get the special programs you
 need
to run certain diagnostics, and procedures on your PS/2, but you do get a
 100%
compatible DOS.  Buy whichever you think you will need, PC-DOS should be
more than 98% compatible with anything MS-DOS has, but if you have someth
ing
in that 2% incompatible area the decision is practically made for you.

Another note is that DOS is on its way out in the form we know it today.
The routines and procedures are being incorporated into GUIs (Graphical
User Interfaces) like Windows, OS/2, and of course as always UNIX.
If you are still one holding out on running Windows or OS/2 you really
should start as soon as you get far behind in the realm of OS's and it
will be hard to catch up.

Actually DOS is out...run Windows 95/98 or UNIX/LINUX if possible and don
't
worry about it unless you are running applications that rely on a DOS ver
sion
that does not run under Windows 98 or UNIX/LINUX or you need a low disk s
pace
OS. 


Q)  8.4  Can I run Windows?  What would I need?

Any PS/2 with the basic requirements can run all of the standard OS's,
such as OS/2 and Windows, even Windows for Workgroups and Win95.  Just
make sure you read the box carefully and that your machine has all the
requirements.  Even though Windows and other OS's can run in 2-3 MB it
is wise to at least have 4MB and 8MB is a more comfortable range.  Try
to get as much RAM as possible as the more RAM you have the faster/more
efficiently your machine will run.

One system.ini line that should be added for the PS/2 user is under the
Enh 386 section, add the line InitPS2MouseAtExit3DFalse.  This prevents
Windows from reinitializing the mouse on a PS/2 and thus causing a 5-10
second delay.


Q)  8.5  Can I run Win95/98? What would I need?

For Win95 if your system meets the CPU, memory and hard drive space
requirements (386DX20 or better, 4MB, and 10-87 MB of hard drive space + 
14MB
- system memory for the swap file)...Load it and go.  That is really all 
there
is to say.  The one thing Microsoft has down is making it easy to install

their software.  If you can run 3.1 or 3.11, Win 95 should also work and 
be
faster.

As to Win98, the I have heard it does not support the PS/2 line well and 
to
avoid it.  Louis Ohland recently stated this too.  I still run Win95 on m
y
regular machines as Win98 seems abrasive to me.  There is nothing OSR2 do
es
not have that I would want from Win98.  BTW if anyone has OSR2.5 (or the
latest version) I really would like it.

Special solution to XGA/2 related problem (happened on Model 77, don't kn
ow if
other models are effected).  From pester69@hotmail.com

I've got a tip I found out about from ps2guru@geocities.com.

Scenario:
You've got a PS/2 77 running xga2 and Win95 but when you shut down to dos
the screen goes completely blank.

Solution:
1) Go into Windows Explorer, look in the "windows" folder for an icon mar
ked
"Exit to DOS".
2) Using the right mouse button, click the icon, and choose "properties".

3) Click the "Program" tab.  In the "cmd line" box,place the cursor at th
e end
of the
   C:\...command.com, add a space, then the switch "/k mode co80". Click
"Apply", then "OK"


Q)  8.6  Can I run Linux now?

Almost 100% of the time providing you are at least running a 386.  Almost

every SCSI card is supported.  And if you can't run the latest kernel the

invaders kernel (ftp://invaders.dcrl.nd.edu) usually will run and is very

full-featured itself.

Please note these PART NUMBERS tend to change and if you have a IBM part
simular to what is listed here, but with a different IBMPN then call
800-772-2227 for a cross-reference.  Also some options listed may work in

other machines, but are not called for per IBM, in general if it works it
works. I would recommend a comp.sys.ibm.ps2.hardware post though before
buying something expensive on speculation that your PS/2 is 'close enough
'
to another for compatability (if you are buying used equipment, IBM PC
Direct offers 30-day unconditional money-back returns if purchased throug
h
them).

Below is a list of nineteen audio cards for the Micro-channel computer.  
    
Twelve of these Audio cards are known to be out of production and are not
    
currently available.  These are labeled "(No longer in production)" after
 the
product name.                                                            
    

While some cards are no longer on the market as new, you may have some lu
ck  
locating a dealer with old stock (slim chance), or find one used in the  
    
classifieds somewhere.  Older sound cards may not have 16 bit stereo and 
other
features found in newer sound cards.  Be sure to verify what you are gett
ing
and what your programs require to avoid any suprises and disapointments. 
    

Note that not all sound cards are suitable for game play.  Some are desig
ned 
for business audio needs only.  Look for cards labeled as "Sound Blaster 
    
compatible" if you wish to play games with the card in question.  Note th
at  
Sound Blaster compatibility is not always 100% in cards not made by Creat
ive 
Labs.  What this means is some games may play perfectly, others may not.

New Jersey Fact:
"New Jersey is a small state on the eastern seaboard halfway between Honest John Lindsay and the Liberty Bell. It is best known for its turnpike, Atlantic City, Imamu Baraka, Newark Airport and the Morro Castle disaster. Most of its leaders are in jail for stealing money...."
