Chapter 27: INT 16H, Keyboard Handler
If an application locks up with both emergency
breakout and Ctrl+Alt+Del disabled, hold down both S
keys and press P for at least 5 seconds to produce a
hard reset. If this does not work, the unit may be faulty:
contact your system supplier for assistance.
AH=24H
AL=matrix code of key
BL=new key code
AL=0 (success) or AL<>0 (failed due to out of range
parameters).
Changes the key code generated by typing the key
specified by AL. Each key code is then translated by
the INT 9 interrupt handler, into a scan code (which is
inserted in the keyboard buffer) or into an immediate
action (such as toggle caps lock or turn off).
The matrix codes and key scan codes are summarised
in Appendix E.
The standard key matrix is restored on a cold start.
You can also restore the default keyboard by using
function 25H.
AH=25H
AL=0 (success) as cannot fail.
Restores the default keyboard mode. This will mainly
be used after the keyboard has been redefined by
using function 24H.
The default keyboard mode is also restored by a cold
start.
