Command: stackshigh

  STACKSHIGH adds stacks to handle hardware interrupts.
  STACKSHIGH is a CONFIG.SYS / FDCONFIG.SYS command.

Syntax:

  stackshigh=nn,mmm

Options:

  nn   The number of stacks in the range 8-64 and 0.
  mmm  The size of each stack, in bytes, in the range 32-512.

Comments:

  This command is not needed on standard installations.
  STACKSHIGH changes number and size of hardware interrupt stacks
  available. nn is number of different stacks and mmm is size in bytes
  of each one.
  In some cases you can use "stacks=0,0" to use only standard stacks
  instead of letting DOS allocate extra stacks for hardware interrupts.
  STACKSHIGH is like STACKS, 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.
  STACKSHIGH is a command internal to kernel.sys and needs no other
  file in order to work.

Examples:

  IN CONFIG.SYS / FDCONFIG.SYS:
    stackshigh=16,256
