DOS/WINDOWS Device Driver & MSCDEX File Appendix C
C-4 Software Driver Installation Guide / Owner’s Manual
Modifications to the AUTOEXEC.BAT file
The INSTALL Program also modifies or creates an AUTOEXEC.BAT file to add
an instruction that tells DOS to invoke the MSCDEX.EXE file with its correct
parameters. This allows the system to communicate with the CD-ROM drive.
MSCDEX /D:MSCD000
MSCDEX.EXE command line switches:
Switch Description Example
/D: Specifies the device name of the /D:MSCD000
(device name) CD-ROM device. This name MUST
agree with the device name declared
in DRD600.SYS
/M:n Specifies the number of cache /M:24
buffers for MSCDEX to allocate.
/E Tells MSCSDEX to use EMS
(Expanded) memory for the cache
buffers. If EMS is available, this can
save lots of RAM.
/L: Specifies for MSCDEX the drive /L:M
(drive letter) letter to start assigning the CD-ROM
discs.
/V Provides memory usage statistics
on how much memory is used by
buffers, memory resident code, and
resident data.
/K Tells MSCDEX to use Kanji file
structures if present.
/S Tells MSCDEX to patch DOS to
allow sharing of CD-ROM drives
on MS-NET based networks.
