This article describes the command-line switches for Microsoft's CD-ROMExtension, Mscdex.exe, versions 2.21, 2.22, and 2.95.

Mscdex.exe is available from CD-ROM vendors, with the MS-DOS 6 Upgrade, 6.2Upgrade, and 6.21 Upgrade, and with Windows 95/98.
Mscdex.exe is a CD-ROM "redirector." It hooks into the MS-DOS or Windowsoperating system the same way the network redirector does to obtain accessto files that are not on local hard or floppy disks. As far as MS-DOS orWindows is concerned, CD-ROM drives look just like network drives.MSCDEX splices itself in front of the network redirector and takes requestsbelonging to CD-ROM drives and passes the rest to redirectors (such asnetwork redirectors).

Command Line Switches

The following is the command line for MSCDEX.EXE:
MSCDEX.EXE: /D:x /M:n /E /V /L:x /S /K
The following table defines the MSCDEX.EXE command-line switches:
Switch                  Definition/D:<device name>        - Allows you to specify a name for the device                          driver. This name must be identical to the                          device name used in the CONFIG.SYS file./M:<n>                  - Specifies the number of sector buffers used                          to cache the path table of a CD-ROM disk.                          Typically, each drive should have a minimum                          of four to five buffers. The larger this                          number is, the less your computer will have                          to read directly from the CD-ROM drive./E                      - Tells MSCDEX.EXE to use expanded memory if                          your system is using expanded memory./V                      - Displays information on memory usage                          when you boot your PC./L:<drive letter>       - Allows you to specify the letter you want                          to assign to the first CD-ROM drive./S                      - Allows the CD-ROM to be shared on MS-NET                          based systems./K                      - Tells MSCDEX.EXE to use any KANJI (Japanese)                          file structures, if present, rather than the                          default of alphanumeric file structures.
