Hi all.  I was fooling around with extended keyboards the other day,
specifically with the extended bios calls and I ran into a weird problem. 
The problem was that I could figure out (although in perhaps an unportable
fashion) whether a given computer had an extended keyboard or not by playing
with INT 16 with AH = 0x11 (check extended keyboard status).  This worked
fine on a Wyse 386, a Samsung 286, and an IBM/PC AT all with extended
keyboards.  It also worked on an IBM PC with a normal keyboard, but it
didn't work on an IBM PC with an extended keyboard.

I also looked through the Waite Group's DOS Developer's Guide and MS-DOS
Advanced Programming from Sybex but neither gave anything as far as the
detection of extended keyboards goes.

Does anyone out there in netland know of a small routine to determine
whether the keyboard connected to any given machine is extended or not?

Keith
