Reference from Microsoft MS-DOS cmd help

Description

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

Parameters

Remarks

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.

Examples

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
