This is a very simple bug but many people don't think about it.
When your building a new PC and use a Phenom II processor(or any other processor) and your BIOS doesn't support it you need a OLDER CPU that fits into the slot to UPDATE THE BIOS. The reason I'm picking on new build's and phenom II is that this is where it's most likely. Since AMD hasn't had a advantage in CPU's since the Athlon 64 most people don't have a AM2/AM2+ compatible CPU and if they build a new PC with a Phenom II chances are that the mobo might need a BIOS update and they can't update with the Phenom II so they're stuck.
