-> Win95 is accessing the CD-ROM drive on my 755CD in "compatibility
-> mode". I would like to eliminate the IBM driver and MSCDEX, but none
-> of my attempts have worked. Has anyone figured-out how to do this
-> after Win95 has been installed?
->
-> Assistance or pointers will be greatly appreciated!
The text file within ftp://ftp.pcco.ibm.com/pub/mobiles/tpwin95.exe explains
how to do this, but it sounds like you may have already tried this
unsuccessfully. I know it worked for me... Here's the excerpt:
5.1.5. CD-ROM Device driver (ThinkPad 755CD or other CD-ROM model only)
-----------------------------------------------------------------------
Windows 95 comes with a generic ATAPI CD-ROM driver and it works
with the ThinkPad integrated CD-ROM. However, DOS/Windows version
of IBM CD-ROM driver is not removed, if you upgrade to Windows 95 beta
from DOS/Windows with IBM CD-ROM driver loaded. The CD-ROM is still
visible in this case but you lose speed and some functionality which
Windows 95 generic ATAPI driver provides. The generic Windows 95
CD-ROM driver is automatically installed if you don't migrated from
DOS/Windows or you migrated from DOS/Windows but without IBM CD-ROM
driver. To make sure that you are using Windows 95 generic ATAPI
CD-ROM driver, do the following steps.
1. Go to MS-DOS command prompt
2. Edit CONFIG.SYS
3. Look for IBMTPCD.SYS in CONFIG.SYS
<example>
DEVICE=C:\xxxxxx\IBMTPCD.SYS /D:TPCD001 /P:170 /R
(Note xxxxxx is the name of subdirectory where you installed the
CD-ROM driver)
If you find it, add "REM" before this statement to comment it out;
save CONFIG.SYS.
If you cannot find it or it's already REM'd out, quit and go to
the next step.
4. Edit AUTOEXEC.BAT
5. Look for MSCDEX.EXE in AUTOEXEC.BAT
<example>
C:\xxxxxx\MSCDEX.EXE /D:TPCD001 /M:15
(Note xxxxxx is the name of subdirectory where you installed the
CD-ROM driver)
If you find it, add "REM" before this statement to comment it out;
save AUTOEXEC.BAT.
If you cannot find it or it's already REM'd out, quit and go to
the next step.
6. Exit DOS command prompt; Reboot the system.
Make sure you're running a BIOS with Plug&Play support: 1.30 or 1.40. It
probably helps to have the CD-ROM actually in the machine for the reboot,
although strictly-speaking this shouldn't be necessary if PnP works right.
