MSCDEX.EXE
MSCDEX.EXE is Microsoft’s CD Extension and is used to interface your PC to the CD-ROM
drive. For the CD-ROM drive, MSCDEX.EXE version 2.21 or above is required.
During installation, a line is added to your AUTOEXEC.BAT that loads the MSCDEX.EXE
driver. The entry in your AUTOEXEC.BAT will be something similar to:
C:\DOS\MSCDEX.EXE /D:MSCDD001 /V
The entry follows the format of:
[drive:\][path\]mscdex.exe /d:device_name [/l:letter] [/m:<number>]
Note: This line is not necessary if your are using your CD-ROM under Windows 98/95.
