Can I suggest that you avoid using getkey, and read the keyboard interrupt
(int 0x09) instead?  If you've ever had the misfortune to play X Wing on
keyboard, you'll know what I mean - the bios routines are slow, and when
playing X Wing, you have trouble blasting anything because the keyboard
buffer fills up and all you get is the BIOS beeping at you.
