LastDrive/LastDriveHigh

Used to designate the maximum number of drives (real and virtual) recognized by the operating system.

The LASTDRIVE command can only be invoked from Config.sys.

Syntax:

LASTDRIVE=x

LASTDRIVEHIGH=x

x A drive letter from A to Z representing the last valid drive that MS-DOS is to recognize.
(Default is Z)

Notes:

If the DOS command is used to manage the upper memory blocks (it usually is), the default values for LASTDRIVE are automatically loaded into the HMA. ie. the line
LASTDRIVEHIGH=z
is invoked without needing to be explicitly stated.

If you should have any comments or suggestions,
please contact: Bob Watson.
