Command: stackshigh

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




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.


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.


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