 It is said that BIOS is very poorly documented. Recently I have been able
to find some information about BIOS data area $40:0 - $40:$84. But I still
have some problem with some of them. Especially about keyboard buffer info-
mation. 
     There are 32 bytes starting at $40:10 for keyboard buffer. Where is
information on how many keys are still in the buffer and where do they
start (As I know they do not always start from the first byte)? 
     This question is very important since I'm designing a software in 
which I need to send a string to the keyboard buffer to mimic actual    
keystrokes. Is anybody expert at BIOS?
