Two posible problems:
1. disable the busmaster:
recommended by IBM
BASEDEV=IBM1FLPY.ADD /A:0 /FORCE:1 /U:0 /F:1.44MB
BASEDEV=IBM1S506.ADD /A:0 /!BM /U:0 /ATAPI /FORCE
2. Wrong sequence in mwave in config.sys. This can lead to very very
wait times for the disks. Default it is installed WRONG!
P.S. Uit is dutch for from.

instructions for PC Card Director
This document is for the TP 365X/XD, 560/E,
760E/ED/EL/ELD/X/XD, and 765 series.
- Place $ICPMOS2.SYS above Mwave device drivers in
CONFIG.SYS if Mwave device drivers are installed and
$ICPMOS2.SYS is located below them.
Uit: ThinkPad 760 - Installing PCMCIA Token
Ring under OS/2
The following is a basic guideline from the ThinkPad
of installation and available resources.
1) Follow instructions for Installing Warp
DO NOT INSTALL NETWORK SUPPORT
DO NOT INSTALL OS/2'S PCMCIA SUPPORT
2) Install PC Card Director for OS/2. DO NOT CONFIGURE THE
TOKEN RING CARD IN AUTOCONFIGURATOR
CD - Rom and other drive letter considerations:
PC Card director installation by default adds drive letters for
Flash and SRAM storage device support with no GUI means of
This may change your CD ROM drive letter.
On a Warp Connect preloaded image the necessary drives are
At minimum - REM out
BASEDEV=PCM2ATA.ADD /S:2 /]DM /NOBEEP :Storage Driver
for OS/2 (ATA)
Can also REM out
BASEDEV=OS2PCARD.DMD : Storage Driver for OS/2
DEVICE=x:\THINKPAD\PCMSSDIF.SYS :Storage Driver for
DEVICE=x:\THINKPAD\PCM2SRAM.SYS :Storage Driver for
DEVICE=x:\THINKPAD\FLSH2MTD.SYS :Storage Driver for
OS/2 (FLASH MTD)
DEVICE=x:\THINKPAD\PCM2FLSH.SYS :Storage Driver for
6) For Machines with MWAVE
- Adjust COM.SYS
At the end of the line \OS2\BOOT\COM.SYS add (2,2F8,3)
The (2,2f8,3) is necessary to allow OS/2's COM driver to pick
the DSP modem,
which is normally at COM2. If the DSP modem is set to COM1,
- Move the following line to the end of Config.sys or MWAVE may
7. Install Network Support
Install software you are using for network support,
The following is for installing Warp Connect but may be used
- Go to OS/2 System
- OS/2 Warp Connect Install/Remove
- Warp Connect Selective Install for Networking
- Choose Advanced Installation
- Pick Protocol
- Configure the IBM PCMCIA Token Ring Adapter
System Interrupt Level = 9
PCMCIA mode = YES
* Shared RAM address = D800
Default Ring Speed = 16 (if applicable)
Shared RAM Size = 16
* Memory Mapped IO/ROM address = D000
* These memory addresses SHOULD be used on PCI based
machines. Other addresses can be used but these have proven

for OS/2 Warp
For successful coexistence with IBM TCP/IP, IBM LAN Requestor and/or
Requestor for OS/2; all of the MMOS2 and Mwave drivers, with the
exception of the
MWAVEVDD.SYS driver, should come after the TCP/IP lines in the
For CD audio on the 755CD/CDV and 760CD/ED to function, the Auxiliary
must be running from the Mwave for OS/2 folder. This is not necessary
if the CD is
set for Digital Transfer.
Reinstallation of Mwave:
If the Mwave installation becomes damaged and fails to function
properly, it will be
necessary to fully remove all Mwave AND Multimedia support prior to
This is necessary to insure a clean reinstall of all features.
For OS/2 Warp:
Edit the CONFIG.SYS and remove all references to \MWAVEOS2.
Do a Selective Uninstall of Multimedia support and delete the
Mwave folders from the Desktop.
Shutdown and reboot the system.
Use the Drives object to remove the \MMOS2 and \MWAVEOS2
Proceed with the installation as outlined above.
WINOS2 Mwave support can be reinstalled independently of OS/2 support,
OS/2 Mwave support is working correctly, then it is not necessary to
remove/reinstall OS/2 support in order to reinstall WINOS2 support. In
WINOS2 Mwave support does not need to be removed before it is
