Configuring MSCDEX for Multiple CD-ROM Drives

The information in this article applies to:
  • Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22


Microsoft CD-ROM Extensions (MSCDEX) can control multiple CD-ROM drives. To configure your system to do this, you must make some adjustments to the parameters on your CD-ROM driver in the CONFIG.SYS file and to the MSCDEX command in your AUTOEXEC.BAT file.


MSCDEX uses the /D:MSCDxxx parameter to differentiate between the drives. For example, the following commands assign the Creative Labs CD-ROM driver (SBPCD.SYS) to drive m and the external CD-ROM (TSLCDR.SYS) to drive n:



   device=c:\sbpro\sbpcd.sys /d:mscd001 /p:220

   device=c:\scsi\tslcdr.sys /d:mscd000



  mscdex /d:mscd001 /l:m /d:mscd000 /l:n 
NOTE: Because MS-DOS treats CD-ROM drives like network drives, they are assigned sequentially to available drive letters (for example, three CD-ROM drives could be assigned to G:, H:, and I:).
