MSCDEX

Provides access to CD-ROM drives. MSCDEX can be loaded from your
AUTOEXEC.BAT file or from the command prompt. (The device driver that came
with your CD-ROM drive must be loaded from your CONFIG.SYS file. For more
information, see Notes.)

The MSCDEX command should not be used after Windows has started.

Syntax

    MSCDEX /D:driver [/D:driver2... ] [/E] [/K] [/S] [/V] [/L:letter]
    [/M:number]

Parameters

/D:driver1 [/D:driver2... ]
    Specifies the driver signature of the first CD-ROM device driver. The
    driver1 parameter must match the parameter specified by the /D switch on
    the CONFIG.SYS command that starts the corresponding CD-ROM device
    driver

    The MSCDEX command must include at least one /D switch. To install
    additional CD-ROM device drivers, specify an additional /D switch for
    each device driver.

/E
    Specifies that the CD-ROM driver be allowed to use expanded memory, if
    available, to store sector buffers.

/K
    Specifies that MS-DOS should recognize CD-ROM volumes encoded in Kanji.
    By default, MS-DOS does not recognize Kanji CD-ROM volumes.

/S
    Enables sharing of CD-ROM drives on MS-NET or Windows for Workgroups
    servers.

/V
    Directs MSCDEX to display memory statistics when it starts.

/L:letter
    Specifies the drive letter to assign to the first CD-ROM drive. If you
    have more than one CD-ROM drive, MS-DOS assigns additional CD-ROM drives
    subsequent available drive letters.

/M:number
    Specifies the number of sector buffers.
