There is a book out by Microsoft Press called "The Programmers PC Sourcebook"
which has all kinds of interesting information in it, including chips on 
different standard cards and thier port locations.  

It includes most of what you have asked about here I believe.  If you can 
find it in a bookstore and thumb throuhg it you may find it interesting.

It goes up through 1988 as the publish date, so has info on the VGA display
cards.  

Wim.
