Where to find BIOS for BFGTech mobo?

I have a BFGTech 680 SLI. Works like a champ.

Now I go to put a Q8300 chip into it (45nm) and it won't boot. Turns out I need the P33 BIOS. Fine, I'll update it...oh, right, BFGTech is no longer around.

Now I can get the P33 BIOS from the EVGA site...but I have no idea if that'll work. I think these are all just rebranded NVIDIA bios, but I don't know if you can take the P33 BIOS update from EVGA and stick it into a BFGTech mobo...?

Or, is there an archive anywhere of old BIOSes from BFGTech?

I just looked and nothing turned up for a BFG P33 bios. But from the rather limited browsing I just did, it sounds like the BFG board is just a reference design nVidia board. So I think the eVGA P33 bios should be the same. But I also seem to remember that the 680i boards were not compatible with the Yorkfield quads like your Q8300.
