Doing More with Your CD-ROM Drive 4-4
MSCDEX.EXE Settings
The syntax of the MSCDEX.EXE statement in AUTOEXEC.BAT is:
C:\path\MSCDEX /D:device /M:xx [/L:drive] [/E] /V
[ ] in the above statement refers to any optional parameters.
After making changes to the statement, please remember to
reboot your system for the changes to take effect.
The descriptions of the parameters are as follows:
Parameter Description
path
Specifies the directory where the driver is stored.
/D:
device
Specifies the name of the CD-ROM drive.
Installation default is MSCD001.
/M:
xx
Specifies the number of buffers to use for temporary
storage of the most recent data.
xx
ranges from 2 to
32.
The performance of your drive increases with the
value of
xx
.
As each buffer uses about 2 KB of memory,
specifying too many buffers may interfere
with programs that have large memory
requirements.
/L:
drive
Specifies the drive letter assigned to the first
CD-ROM drive. If this is not specified, the next
available drive letter is used by your system.
If you have specified the LASTDRIVE
statement in your CONFIG.SYS, make sure
that the drive letter falls within the specified
range. See Appendix C, “Troubleshooting”
for more information.
/E
Specifies the use of expanded memory. This
parameter is only applicable to Expanded Memory
Manager LIM version 3.2 or later.
/V
Displays RAM allocation and expanded memory
usage at boot time.
