LASTDRIVE= (CONFIG.SYS Command)
Compatibility: 2.0+
Purpose: Sets the limit for drive IDs usable by the Subst command and for
use as InterLink drives.
Syntax: LASTDRIVE=d
█▌Parameters▐█
d is a single alphabetical letter in the range A to Z.
█▌TECH Notes▐█
■ DOS maintains an undocumented internal array of information on each
drive, including the ASCIIZ name of the current directory. The size of
this array is set via the LASTDRIVE= command.
The undocumented DOS fn 52H (get DOS Vars) returns the address of a
DOS Variables Block, one field of which contains the LASTDRIVE= setting
and another field points to a pointer to the drive info array.
