**Intro:
The information contained within this file should not be considered
100% correct. Where possible information has been taken from
datasheets, however even this info may be incorrect. The datasheets
state what the chip should do, not what they actually do. This is,
compounded further by different revisions of chips.
This document will never be complete, and I have no intention of
finding every datasheet for every chip set. Some of the chip sets
listed are from later systems in the PIII/P4/Athlon era. There are
many websites with information on these chip sets and these entries
will likely not be expanded upon. The focus of this document is early
PC/XT to Pentium chip sets. There are few sites that clearly illu-
strate this information, and how they relate to each other.
I aim to prioritize cataloging significant, rare or otherwise
interesting chip sets.
BTW the reason I wrote all of this down, is so that I could FORGET it.
Basically I needed to free up some RAM. I've a head full of arcane
snippets of information on this subject. I don't want to end up a
crazy old man ranting random disjointed information ("The C&T CS8220
came before the CS8221 you KNOW!") to disinterested passersby, unable
to see how senile I've become. A side benefit, this might be useful to
someone else:-)
