I have an OS/2 Warp CD that I am wanting to use as the installation media on an IBM PC 350 Pentium system. I have already installed MS-DOS 6.22 and the IBMIDECD.SYS driver for the CD-ROM drive on the boot HD. When I boot the system, it seems to install the driver and MSCDEX.EXE is loaded and reports drive E: is available (the CD-ROM drive).
The exact driver loading information from my CONFIG.SYS is:
DEVICEHIGH=C:\IBMIDECD.SYS /D:IBMCD000
And the command in my AUTOEXEC.BAT is:
C:\DOS\MSCDEX.EXE /D:IBMCD000 /L:E
I can switch to E:
, and I can use the DIR
command to see the contents of my CD-ROM, but I cannot access any of the files on the CD-ROM. The transcript below shows this "weirdness".

If I insert the same CD into my modern computer, I can see and access all of the contents. Under Mac OS X, the CD is recognized as being ISO 9660 format.
What problems with the CD, CD-ROM drive, and driver setup in MS-DOS 6.22 could possibly be causing this behavior?
