Command: lastdrivehigh
Lastdrivehigh is a CONFIG.SYS / FDCONFIG.SYS command.
Lastdrivehigh sets the last letter to which a drive can be assigned.
Syntax:
lastdrivehigh=x
where x is the last letter that will be available.
Options:
- none -
Comments:
By default, FreeDOS will set x high enough for all floppy drives and
detectable hard drive partitions, plus one for a CD or other drive.
You may want to set x higher if you wish to use more than one drive
that FreeDOS cannot detect automatically (CD drives, zip drives etc.).
Setting x higher than necessary wastes a small amount of memory.
LASTDRIVEHIGH is like LASTDRIVE, except it attempts to load into high
memory first (failing that it should load in conventional memory).
Note: The order you load devices may have a large impact on amount
of free memory available. In general try to load large (in memory
usage) programs into high memory first.
Important: You should have a high memory manager such as (HIMEM),
HIMEMX or JEMMEX installed (prior device=himem.exe or
device=himemx.exe in CONFIG.SYS / FDCONFIG.SYS) before using
this option.
LASTDRIVEHIGH is a command internal to kernel.sys and needs no other
file in order to work.
Examples:
IN CONFIG.SYS / FDCONFIG.SYS:
lastdrivehigh=z enables drive letters from A - Z.
