Well, I don't need a newer bios right now. I'm using the FF one, and it works fine. I have no issues with the system, other than it being slow in its old age (and the video card being total garbage.) I saw that beta bios thread, but didn't see any sort of list of supported CPUs, just that it was a fix for ATI graphics cards - so I thought they would eventually release an updated version that would include new CPUs...
So while I appreciate the offer, I'll have to pass on it. No use trying to fix something that isn't broken, after all!
Thanks folks!
