I have an ASRock N68-S with BIOS P2.10 and i am looking for a CPU, on this list http://www.asrock.com/mb/NVIDIA/N68-S/?cat=CPU there are all the CPU compatible with my motherboard, but as u see many BIOS are different from P2.10. I would like to ask does the CPU's BIOS have to be same with the motherboard BIOS?
