 There are several dozen registers, many of which piggy-back, that is that
 the value you write to one PIO address determines which register you are
 talking to when you write to another. The only complete writeup I have seen
 is the IBM technical reference manual, which is quite obscure. The best
 writeups have been in journals like PC magazine. Try looking through the
 readers guide to periodical literature at your library under IBM or EGA
 for references to exact issues.
