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.
