A dead CMOS battery would just cause you to lose your CMOS settings everytime the PC lost power.
S+H would be about $20 each way for both boards/cpus more than likely. If you don't get any takers soon, feel free to send them my way. I think I've averaged about $9 for each one I've sent out using USPS 2-Day w/ Delivery Confirmation.
I just sent you an e-mail regarding something else, maybe we can work out a deal.
