Not about resetting the CMOS. That would be pointless given the hole in his motherboard. lol
But the oven trick is worth a shot. If the trace is only slightly broken (doubtful) there's a chance he could reflow it by sticking it in the oven. There have been many cases of people fixing their graphics cards and even motherboards by sticking them in the oven. And I've personally fixed an old sound card as well this way. I think I even posted a thread about it.. I'll go look.
In the meantime, here's more info about reflowing a mobo.
