Hmm.....strange. Try this: Shut down and unplug the PSU. Remove the mem sticks and the CMOS battery. Discharge the motherboard by holding in the power button while touching the chassis for approx 30 sec. Put the battery back in followed by the memory then post, see if that helps.
Funny that it works for some BIOS. I happen to came across it back in the old days with my 8RDA+ after updating the BIOS. There were supposed to be new options in BIOS, but I didn't see them. Then I read instruction that suggest with any newly updated BIOS you need to reconfigure everything from ground zero with 'Reset to Default'.
