IWill XP333 Prob

Ok well I think my bios chip is dead. My bro was using it @ a LAN Party w/ me. When we got home I hooked it all back up and its all messed up. I cant even get to where it detects the HDs, so I think the bios is messed up. Where can I get a replacement BIOS chip?

Also, give me a bit and I can build a system with that mobo and get the info it says written down. Thanks.
