Int 16/AH=92h

KEYB.COM KEYBOARD CAPABILITIES CHECK (not an actual function!)

AH = 92h

Return:
AH <= 80h if enhanced keyboard functions (AH=10h-12h) supported

Desc: This function is called by the DOS 3.2 KEYBxx.COM and DOS 5+ KEYB.COM to determine the highest supported keyboard function

Note: Many BIOSes (including at least some versions of Phoenix and AMI) will destroy AH on return from functions higher than AH=12h, returning 12h less than was in AH on entry (due to a chain of DEC/JZ instructions)
