These are very helpful links! I've learned quite a few things about my
processor by looking them over. The UM4980 link is down for the moment, but
hopefully soon I'll be able to find out what JP1 is.
Thanks!

Hi Drew,
Perhaps the manual could help. Also the individual that runs this page
appears to offer help to those like you who are working with this
motherboard. Why not give the manual a try and see if there is something in
there that can help.
Copy of UM4980 manual.
http://members.home.net/pbuick/um4980/page1.htm
Also there may be some interesting things to try at this page.
http://www.amd.com/support/faqs/486faq.html
If you would like to get an updated bios for the board.
http://www.ecs.com.tw/download/bios.htm
There are plenty more places to go if you wish. Just search google. Google
is your friend ;)
Have fun,
