                                 LASTDRIVE

Specifies the maximum number of drives you can access. You can use this
command only in your CONFIG.SYS file.

The value you specify represents the last valid drive MS-DOS is to
recognize.

Syntax

    LASTDRIVE=x

Parameter

x
    Specifies a drive letter in the range A through Z.

Default setting

If you do not use the LASTDRIVE command, the default value is the letter
following the last one in use. For example, if you are using drives A and C,
the default value is D.

Effect on memory

MS-DOS allocates a data structure in memory for each drive specified by
LASTDRIVE, so you should not specify more drives than are necessary.

                                      ***

                             LASTDRIVE--Example

To set the last drive to M, giving your computer access to 13 drives, you
would include the following command in your CONFIG.SYS file:

    lastdrive=m

                                      ***
