Er, what is it you're trying to achieve?  The keyboard buffer doesn't
have to fill before characters are available to a running program.
When a key is pressed, int 9h decodes it and places it into the buffer.
This is, for all practical purposes which I can imagine, instantaneous.
The key can then be read by calling the bios routines under int 16h, 
which are, if anything, faster than int 9h.  What's the problem?
