Command: keybuf
KEYBUF relocates the keyboard buffer from the default location at
0x40:0x1e-0x3e to 0x40:n-m.
KEYBUF is a CONFIG.SYS / FDCONFIG.SYS command.
Syntax:
keybuf=n[,m]
where n is in 0xac-0xde or 0x106-0x1de range and m is <= 0x200
Options:
- none -
Comments:
KEYBUF relocates the keyboard buffer from the default location at
0x40:0x1e-0x3e to 0x40:n-m. The buffer must be more than 32 bytes and
must not touch offsets 0x100-0x105.
Default for m is "next multiple of 0x100 after n".
Note: Some BIOSes store data in the 0xac-0xff area. BASICA will use the
0x106-0x120 area. Other hardware, drivers or apps can collide with
KEYBUF, too, so use it at your own risk.
A reasonably safe choice should be "keybuf=0x140,0x1c0".
KEYBUF is a command internal to kernel.sys and needs no other file
in order to work.
Examples:
IN CONFIG.SYS / FDCONFIG.SYS:
keybuf=0x140,0x1c0
