=============GENERAL INSTALLATION PROBLEMS=======================
1. 5.25" diskette problem:
Install program asks for disks 16, 17, and 18 during
3.5" diskette install.
The CMOS was not changed to view the A: disk
as a 3.5" 1.44MB disk drive.
Run the hardware SETUP program for the machine.
If running AMI Bios, Press the DEL key at system
bootup time. Press ENTER on the first selection
"Standard System Setup". Press ENTER on the
"warning screen". About half way down the screen
is the A drive setting. Use PGUP or PGDN to
select 1.44MB. Hit ESC. Choose "Write to CMOS
and EXIT" with the cursor, press ENTER. Answer
'Y' to the question "Write to CMOS and EXIT?".
From here the machine should be setup correctly.
The user can then proceed to place the OS/2
installation diskette in drive A and proceed with
the install again.
2. AMI Bios version problem
Various install problems. The suggestion to upgrade
these items should always be made. Possible SYS2025,
and SYS2027 at disk#1.
Machine must have BIOS dated 5/9/91 and keyboard
controller chip version KF. The following information
will be seen by the user at (cold)boot time:
AMI BIOS and AMI BIOS Plus:
AMI Hi-Flex BIOS:
If an IDE hard drive is in the system, "mmddyy" should
be 040990 or later. For other drives including MFM,
RLL, ESDI, or SCSI, "mmddyy" should be 092588 or
later. Controller chip version can be located on the
bottom of that same screen. Check the last digit in
the long stream of digits (the "c" above). The last
digit will probably be either be 8, B, D, or F. The
required level should be F for OS/2 v2.0 or v1.3.
Pressing the INS key during bootup should cause this
info to stay on the screen.
1. Call Washburn & Co. to order new versions.
2. Bad diskette. Format new diskette and diskcopy
failing diskette to this new diskette.
3. Clean, swap or replace the diskette drive.
4. Disable system memory cache during installation.
3. Phoenix Bios version problem
Same as #2 above.
Not yet determined what the required level of BIOS
is, but Version 1.02.05D seems to work good on a
variety of machines.
Contact hardware vendor, or Phoenix for more info. If
you do not have the above version, please call Phoenix
and get to at least that level.
4. IBMS1506.ADD problem
Not sure at this time.
Not sure at this time.
Get new IBMS1506.SYS.
5. Memory problems on a Model 90/95
Downlevel processor card/memory riser card.
If your processor card has part number 84F9356
then it should be replaced.(ECA-053) If your
memory "riser" card is part number 84F8157, 84F9356,
or N33F4905, then it should be replaced.(ECA-084)
6. Install hangs at "Loading please wait..." message.
Install hangs at "Loading please wait..." message.
Possible BAD memory.
Get new SIMMS. Make sure that the new SIMMS are
matched in speed and type.
7. At Disk#1 install reboots computer or internal processing error
When diskette #1 of install process is inserted in
drive the machine will reboot, or cause an internal
Replace memory with good memory.
8. FDISK errors, slow installation, grinding noise from HDD.
FDISK unsuccessful error on Disk #1, VERRYYYY slow
installation, or unusual noises coming from hard
drive. May also experience an "Internal Processing
Error" within the first two diskettes.
Incompatible hard disk driver. This problem appears
on AT bus machines with RLL, MFM, and ESDI drives.
If the hard drive has more than 1024 cylinders, be
certain your hard disk adapter's sector translation
mode is enabled.
If you are unsuccessful in getting OS/2 installed
because of the above problem, please follow these next
steps on Diskette #1 of OS/2 install set. (You should
make a backup DISKCOPY of your install diskette before
modifying anything). Using a text editor, modify the
CONFIG.SYS file on Diskette #1(the copy). Make the
following modification to CONFIG.SYS:
Boot the Installation Diskette, and proceed through
the installation procedure through the first five
diskettes, then reinsert the Installation Diskette as
directed. Then after files have been copied from the
Installation Diskette the system prompts you to
remove the diskette and press ENTER to reboot. Do
so, but immediately reinsert the Installation Diskette
as soon as the SCREEN clears. Insert Diskette #1 and
press ENTER when prompted. At the next screen, press
ESC. At the OS/2 command line, type:
RENAME x:\OS2\IBM1S506.ADD IBM1S506.XXX
COPY x:\OS2\IBMINT13.I13 x:\OS2\IBM1S506.ADD
replacing x: with the appropriate drive if you are
installing elsewhere. Remove Diskette 1, then press
CTRL-ALT-DEL to reboot to finish installation.
Installation should flow smoothly from here on.
9. COUNTRY.SYS not found
COUNTRY.SYS error message at bootup of first two
diskettes or after first five diskettes, and reboot
of machine by installation program.
Invalid device driver for hard disk being used. Seems
to occur more often on non-IDE/SCSI drives. More
prevalent on ESDI/MFM/RLL drives. Country.SYS error
messages almost always point to OS/2 not being able to
recognize the hard drive media.
Resolution: Follow instructions in #8 above.
|10. COUNTRY.SYS not found
COUNTRY.SYS not found error message while installing.
Possible conflict with another device on the machine.
Disconnect any tape backup, CD-ROM or other devices
not needed for installation. Reconnect once
installation is complete.
|11. COUNTRY.SYS not found on a P70
COUNTRY.SYS not found error message while installing
on a P70.
Contact your IBM CE for ECA068. This is indicative of
a problem recognizing the disk. ECA068 should remedy
|12. ERROR number 60002,9084
Trap on installation with error message 60002,9084.
Possible bad memory.
Try removing SIMMS one at a time(if possible) and try
installation until it works. Otherwise have your
hardware dealer/service personnel check and/or replace
|13. Installation locks up at start of graphical install
After first set of diskettes is installed and
installation program warm-boots the computer, the
graphical install portion does not appear. Rather the
machine hangs at this point.
Video card may be in set for non standard VGA mode, or
autosense capability on the card not working correctly
Make sure video card is in VGA mode with auto-sense
|14. Problem installing on a ZEOS notebook machine
Installation fails on this machine. Can be attempted
on other machines that also hang very early during
Unknown at this time.
The customer must have access to (a running version
of) OS/2. A patch must be applied and it MUST be
applied using OS/2. The instructions for applying the
1) Make a backup copy of the INSTALL diskette
2) With the diskette in drive and from
the A: prompt type:
3) When asked for the offset address:
4) On the line shown, enter 45 to replace 44
as the first byte in the line and
5) When asked if you want to continue
6) When asked to apply patches:
7) At the prompt type:
8) Install OS/2 using the new patch diskette.
|16. AOX Systems
AOX system has problems installing or booting OS/2.
Outdated "flash-prom" code.
Call AOX support and ask for the latest "flash-prom"
|17. Gateway 2000 machine locks up
Machine locks up. No further details available at
Micronics motherboard with revision level E or
prior needs to be upgraded to level F.
Call Gateway for upgrade. 800-523-2000.
|18. Receiving 111 Error message with MicroChannel machine
Receive a 111 message at system bootup time on PS/2
Channel Check on the microchannel. A card installed
in your system has detected some sort of memory
problem. This does not necessarily point to actual RAM
SIMM problems but can be generated by any card on the
Have system checked out by IBM SERVICE. See phone
number above for outside customers.
|19. Not enough RAM installed
1. SYS0318:Message file cannot be found. (customer
had 2 MB memory)
2. Sys????:The system cannot load the DLL,
QCALLS..... (customer had less than 4 MB memory)
Install at least 4MB RAM Silly! May need to disable
system cache also? If 4MB is installed.

Add the following statement in the CONFIG.SYS:
Once these steps are taken, reboot the machine to initiate the
Following are a number of notes about usage, and
about potential compatibility problems with the
microcode levels on various adapters and devices.
Adapter: All Adaptec adapters
Note: SCSI hard disks must be configured as SCSI target ID 0 or 1
to be able to start up from that hard disk.
Adapter: Adaptec AHA-154x
Drive: IBM 0661 - 320MB SCSI
Note: Adapter BIOS will not recognize the drive as Target 0 or 1
(Drives 80, 81). For OS/2 2.0, the drive can be used as a
Adapter: Adaptec AHA-174x
Drive: IBM WDS-3180 - 80MB SCSI, IBM WDS-3160
- 160MB SCSI
Note: Adapter will not recognize these drives when configured in
'STANDARD MODE' (AHA-154x emulation). Instead, the
AHA-174x adapter should be configured in 'ENHANCED MODE'.
This mode is supported by the OS/2 2.0 drivers, and the
problem does not occur when the adapter is operating in
Adapter: Future Domain TMC-850/860/875/885 w/BIOS revision level
Future Domain TMC-1660/1670/1680 w/BIOS revision level 2.0.
System: IBM Models 35 and 40 when the Future Domain adapter is
controlling the startup diskette.
Note: Will produce the message, "Disk read error has occurred"
when you attempt to start the Installation diskette.
Contact Future Domain for a free BIOS upgrade.
1. AMI SCSI Adapters
AMI "Fast Disk" and AMI "Fast Disk II" SCSI adapters
are incorrectly recognized as Adaptec adapters.
At the final restart after the installation is
complete, delete from the CONFIG.SYS file, any
line with "BASEDEV=AHA1xxx.ADD" (where "x" can
be any character). Ensure the line,
"BASEDEV=IBMINT13.I13," appears in the CONFIG.SYS
2. Problems with Always IN2000 SCSI adapter
| Internal Processing Error.
| Bios adapter with bad bios. Bios level of 3.06A
| or 3.20 should be upgraded. The current BIOS level is
| VCN:1-02 and works with OS/2 v2.0.
Upgrade to current BIOS level of VCN:1-02. Also,
Always IN 2000 SCSI Host Adapters may require an
EPROM upgrade from Always for $20 to operate with
V2.0. The revision level should be 2.5-2.7 to work
properly. The dividing line is not clear, and at
least one customer was not helped by the EPROMS,
though several others were. Always suggests installing
the EPROMS and re-formatting the drive - seems to be
some problems installing over DOS partitions. Always
can be reached at 818-597-9595. The customer who was
NOT fixed by the EPROMS was unwilling to re-format.
Symptoms of the problem are varied, but the most
common is an FDISK error on the second diskette.
|3. Bernoulli Boxes
44 and 89MB drives will work if connected to any other
SCSI card other than Bernoulli's own card. The drive
will work as a large diskette and will be
|4. PROCOMM+ SCSI MCA adapters do not work
Contact PROCOMM for details on OS/2 support.
|5. Slow SCSI support or missing icons
Slow hard drive speeds and possibly no icons
appearing. Other data corruption possible.
Hard drive and adapter card settings not correctly
Ensure that hard drive and card are matched in their
settings of SYNCH and ASYNCH mode.
|6. IBM 16-bit SCSI cards(early versions)
Early versions of the IBM 16-bit SCSI adapters may
experience problems and report erroneously that the
device is not functioning.
Replace SCSI card with a card with updated microcode.
|7. Quantam Plus Hardcard
Numerous failures under 1.3 and 2.0.
Microcode lower than 2.6 will cause numerous failures
under 2.0. Also, drive cannot be second disk if
installation will take place on the hard card drive.
Call Quantum about EPROM upgrades. Note: They will
deny the problems being theirs!

2. Out of Synch/Install problems
Addressing of card in 16-bit mode.
Switch card to 8-bit mode if available. This
will probably involve setting a jumper, or dip
switch according to the documentation that comes
with the card.
3. Video Cards using TSENG TC6059AF chip(ET4000/see below)
Problems going from DOS SVGA -> PM VGA Desktop
Some hardware register not handled correctly by
the GA version of the VSVGA.SYS driver.
Get new VSVGA.SYS.
4. Trap E switching a DOS fullscreen to a window
When I window a DOS fullscreen running in
SVGA I often get a Trap E. Will be prevalent
on overcommited (low-memory) systems. The PM
driver you are using can also have an effect.
Get the new VSVGA.SYS.
5. Trident 8900B Card
Hardware problem with these cards.
Call Trident. Phone number: ?
6. Trident 8900C Card
System hangs with blinking cursor in the upper
right hand corner.
PMI file usually not created properly.
See "HOW TO REGENERATE PMI FILES" below:
7. Trident 9000 Card
DOS/PM screen Synch problems possible. Running
SVGA ON does not help.
Follow the "HOW TO REGENERATE PMI FILES"
8. Video Corruption returning to WIN-OS2 session
Video becomes corrupted when returning to a
previously opened Full screen WIN-OS2 session.
WIN-OS2 session not aware that a video mode
switch has taken place.
Set your VIDEO_SWITCH_NOTIFICATION in the DOS
SETTINGS to ON.
9. Colors of Windows applications appear distorted
Windows applications running on the OS/2 Desktop
appear different than in a WIN-OS2 fullscreen.
The DOS/Windows application's colors have to be
translated to use the OS/2 PM color palette.
With the OS/2 VGA Desktop, there is a limitation
of 16 colors. This colors simply cannot be
Run the application fullscreen, or obtain a PM
driver that can support more than 16 colors.
10. Installation of OS/2 halts at Blue "IBM Logo" screen
OS/2 boots up to Blue IBM Logo screen and does not
finish printing "INSERT DISK #1 message". Drive
light continues to stay on indefinitely.
Incompatible OAK Video card.
1. Temporarily use another VGA card to get OS/2
installed. Should be able to place card in after
2. NOT VERIFIED: This should only be tried by more
a. Make backup copy of INSTALL disk.
b. Un Write-protect INSTALL disk.
c. Boot up DOS and put INSTALL disk in drive A.
d. COPY A:OS2LDR A:OS2LDR.OLD
e. DEBUG A:OS2LDR
f. U 4F7C
g. E 4F7C
m. Use new install diskette to install OS/2.
Note: The install will no longer display text
on the blue screen that comes up after install
diskette is inserted. When the blue screen
comes up, insert disk 1 and continue.
HOW TO REGENERATE PMI FILES:
Start up a DOS FULLSCREEN session and type "SVGA ON".
This will create a file called SVGADATA.PMI. You can
then exit the DOS FS, and shutdown OS/2. At boot time,
this file is read(if present) by BVHSVGA.DLL. You need
to verify that the following statements appear in the
Note: A PMI file tells OS/2 (BVGSVGA.DLL specifically)
the capabilities of your video card, resolutions

your adapter. Try some of the suggested variations in your
I'm getting some corruption returning to my WinOS2 fullscreen
Set your VIDEO_SWITCH_NOTIFICATION in the DOS SETTINGS to ON.
1. Mouse driver does not install correctly
No mouse pointer movement(or no mouse pointer).
Either the install program could not correctly
determine what type of mouse it was, or could not
determine that a mouse was indeed present. If the
user had mouse support during the graphical install
portion of the installation process, then he probably
changed the mouse driver/port that OS/2 had already
chosen for his configuration.
Have the user run the Selective Install program found
in the OS/2 System/System Setup folder and choose a
different driver. See below for further suggestions.
2. Mouse does not work after Dual boot
After performing dual boot to DOS, mouse does
Mouse has a "memory" that remembers the mode it
was in previously.
Before performing the dual boot, open a DOS
window or fullscreen and type MOUSE PC. You can
also perform a cold boot after issuing the BOOT
/DOS command. The third suggestion is to unplug
and plug it back in after a few seconds (this
allows the mouse to be reset).
|3. HP Mouse installation
1) Select any mouse during installation
2) Copy HILMOU.SYS and NOEXBIOS.SYS to C:\OS2\ (these
are supplied the manufacturer)
3) Modify CONFIG.SYS with the following in the order
(THIS LAST LINE SHOULD ALREADY BE IN CONFIG.SYS
BUT WILL NEED "TYPE=HILMOU$" ADDED )
HP Cust Service # is 1-800-752-0900 P#289547
Customer may also go to his dealer for the diskette which
ships with mouse. Customer may also see COMPUSERV GO HP.
|4. Logitech Mice
Logitech mouse does not function under OS/2.
Mouse does not function when installed with the
Select PS/2 style pointing device during install. If
already installed and mouse is not working correctly,
perform a Selective Install(run INSTALL from the
command line) and choose the above mentioned driver.
|5. Alternate pointing devices (two mice!)
There is an undocumented function in the mouse device
driver. If you have some alternate pointing device
such as a tablet or touch screen you may use it in
addition to the regular mouse pointing device.
1) Install the device driver for the device with the
appropriate DEVICE= statement in CONFIG.SYS (this
must be an OS/2 device driver.)
2) Add the following to the end of the
Where the xxxxx$ is the name of the device (from
the device driver manual)
3) Upon reboot, both pointing devices will be active.
6. For General Mouse driver info:
Type HELP MOUSE at an OS/2 prompt to read about proper
CONFIG.SYS parameters for the mouse drivers.
==========COM PORT PROBLEMS======================================
1. OS/2 cannot see COM3 and COM4.
OS/2 does not recognize COM3 and COM4 installed on an
COM3 and COM4 are supported on PS/2s without any
additional effort. On (E)ISA machines, some additions
are required to CONFIG.SYS.
Using a text editor, include "(port number, base
address, interrupt number)" parameters next to the
COM.SYS and VCOM.SYS filenames. One example:
DEVICE=C:\OS2\COM.SYS (3,3E8,5) (4,2E8,3)
DEVICE=C:\OS2\MDOS\VCOM.SYS (3,3E8,5) (4,2E8,3)
NOTE: These are NOT default parameters and must be
configured according to the user's hardware reference
material for the card where the COM ports reside.
Parameters for COM1 and COM2 need not be included
(unless they are somehow nonstandard). OS/2 must end
up with sequentially numbered COM ports. For
example, if port two is not installed but port three
or port four is installed start numbering using
(2,...) in the DEVICE lines.
The port address cannot be shared. If a port address
is shared by two or more COM port, it will create
Although we may put any preferred values to install
COM 3 or/and 4, the ports or COM.SYS may not be able
to perform as it should be if the values are different
from the ones specified by the COM 3 and COM 4 adapter
cards. For an example, a FAX/MODEM card which can be
configured as COM 4, but the documentation indicates
that the IRQ will be 3 when COM 4 is chosen. If
COM.SYS is installed for COM 2 which uses IRQ 3, there
will be a conflict in IRQ level. COM.SYS will make
both COM 2 and COM 4 available, but both ports cannot
be opened at the same time. If the user would like to
use COM4, it is recommended to disable COM2 or to
remove COM2 adapter card.
2. Problems performing high-speed communications
Using high speed modems (19200+ and maybe 9600), any
interference with OS/2 while downloading/uploading
data(moving the mouse, CTRL-ESC) will result in losing
data or even losing the connection.
Hardware on the motherboard controlling the COM Port
loses interrupts when running under OS/2. DOS is able
to run with the slower hardware successfully since it
can dedicate ALL resources to dealing with the COM
Need to have a 16550 UART chip installed on
motherboard or serial card. Contact your normal
hardware support people to find out if you can have
this done on your machine.
|3. More on problems with high-speed communications
Performing disk I/O can corrupt/interrupt high speed
communications. The machine is configured using the
IBMINT13.I13 driver for his drive.
The IBMINT13.I13 driver is not a high performance
driver since it is for general use by many different
Contact supplier of hard drive to see if there is an
OS/2 2.0 specific driver available for their drive.
1. Cannot print on LPT1 or LPT2
No printing works.
Another adapter is using IRQ7 or IRQ5. Cheap cable not
using all 25 pins. Older parallel port card
which does not support interrupt driven printing.
Make sure no other adapter card uses IRQ7 for LPT1 or
IRQ5 for LPT2(Soundblaster defaults to using IRQ7).
Also make sure the printer cable being used has a full
set of 25 pins. Some older cables do not use all the
pins since in DOS they weren't all used. Under OS/2
all 25 lines can be used. Buy a cheap parallel port
card that does support interrupt driven printing.
|2. HP Scanjet
Error message stating you cannot access the printer.
Switches not set correctly on the card?.
Set EMS_FRAME_LOCATION in the DOS Settings to AUTO.
For AT bus machines:
Set card switches to 1010.
For MCA machines:

The only ones known to work at this time are IBM and
Toshiba CD-ROM drives. If the CD-ROM device is SCSI
with no other devices attached to the SCSI adapter or
is non-SCSI try using a VMBOOT to get this working.
==========TAPE BACKUP UNITS======================================
1. Mountain tape backup units
Above referenced tape backup units do not work

1. Trying to run application(s) results in SYS0005, Access Denied
SYS0005 msg returned by OS/2 when you attempt to
execute a program.
OS/2 is unable to successfully access the file. File
may be corrupted, or bad areas on the disk are causing
problems for OS/2.
Run CHKDSK on the drive. If this is
the boot drive, you will need to boot from the
installation disk, then disk #1. When you get to the
next screen, hit ESC to return to the A: prompt. At
that point, insert diskette #2 into the A: drive and
type "CHKDSK x: /F" where "x" is the drive you are
running the command against(the OS/2 boot drive).
2. SYS3176 when trying to open any DOS session
Simply opening any DOS session results in this trap.
SVGA support having problems with TSENG chip video
cards. Especially with the ET3000 chip based video
There are four things to try:
1. Set RMSIZE = 624 instead of 640.
2. In the DOS Settings set HW_ROM_TO_RAM to ON.
3. Disable SVGA support by changing the
4. The updated VSVGA.SYS driver may help also.
3. FatalExit code x0401 when trying to execute Win-OS2
Above error message whenever WIN-OS2 is started. May
flash by user without user being able to record
error. You can have user start up a DOS Fullscreen
and start WIN at the command line to verify that this
is the problem.
Missing .DRV, or .DLL in the \OS2\MDOS\WINOS2 or
\OS2\MDOS\WINOS2\SYSTEM directory. OS/2 probably did
not install these correctly. (I got this err msg by
erasing VGA.DRV in the SYSTEM directory)
Have user redirect DIR listings of the two
directories above by the command:
DIR > LPT1
Once the user has this information he can go back and
compare his WIN.INI and SYSTEM.INI to see what
file(s) are missing. The INI files are located in
the first directory noted above.

Messages that indicate OLECLI.DLL, OLESVR.DLL,
SHELL.DLL cannot be found running certain Windows apps
under Win-OS2 which had been installed on the actual
Windows 3.0 product.
The above mentioned DLL's are normally installed
along with the application that uses them. The .DLL's
are in the SYSTEM directory under the "WINDOWS"
directory for the Windows 3.0 product.
Reinstall the applications on WIN-OS2 or copy the
DLL's over to the \OS2\MDOS\WINOS2\SYSTEM directory.

SETTINGS for that DOS application.
|8. Cannot get any expanded memory in the OS/2 Dos Environment
The MEM command from a OS/2 DOS session reports no
Hardware base address conflicting with area needed for
expanded memory. Seems that OS/2 may be requiring
that the 64K region starting at C0000 be free in order
for it to correctly configure expanded memory.
Move the hardware base address for any card using the
above address to another address. Consult your
hardware references to figure this out, or run a
hardware diagnostic program to give you the
