Hi Geoff,
Thanks for the reply and suggestion...
I am not familiar with what parts/chips you are referring to as I have
not yet had to deal with the A2 board directly except adding/removing
RAM :)  Can you or someone refer me to a schematic that has info on
where these are on the board?  I will also search for one myself...
I am definitely interested in figuring this out and hopefully fixing
it.
