I'm sure this is old news to many but new news to some,total hardware 99(th99)is a database and can be downloaded onto a local machine as well,it is pretty much the webs biggest collection of white papers on old hardware,if it's a computer or computer related and it's old it's probably covered,this document has saved me many hours/days of frustration and fiddling with jumper settings and many other adjustments.
