MSCDEX--Examples

Loading and enabling a single CD-ROM device driver

This example shows the relevant CONFIG.SYS and AUTOEXEC.BAT commands for a  
computer with one CD-ROM drive.

The CONFIG.SYS file contains the following DEVICE command:

    device=c:\devices\cdromdrv.sys /d:mscd000

This command loads the device driver CDROMDRV.SYS, which came with the
CD-ROM drive. The AUTOEXEC.BAT file contains the following MSCDEX command:

    c:\dos\mscdex /d:mscd000 /l:g

This command enables the device driver that has the driver signature
MSCD000. The /E switch specifies that the driver be allowed to use expanded
memory, if available. The /L:G switch assigns the drive letter G to the
CD-ROM drive.

Loading and enabling more than one CD-ROM device driver

This example shows the relevant CONFIG.SYS and AUTOEXEC.BAT commands for a
computer that has two CD-ROM drives from two different manufacturers.

The CONFIG.SYS file contains the following DEVICE commands:

    device = c:\aspi\aspicd.sys /d:mscd000
    device = c:\cdrom\tslcdr.sys /d:mscd001

Each command loads the device driver that came with that CD-ROM drive. The
AUTOEXEC.BAT file contains the following MSCDEX command:

    c:\dos\mscdex /d:mscd000 /d:mscd001 /l:j

This command enables both device drivers. The first driver has the driver
signature MSCD000; the second has the driver signature MSCD001. The /L:J
switch specifies that the first CD-ROM drive, MSCD000, will be drive J and
the second CD-ROM drive will be drive K.
