I'm having a strange issue on my board, both BIOS chips showing the little red light in the bottom right hand corner of the board with no postcode when using an APU. I don't have any other CPU at hand at the moment, I flashed back both chips to the latest BIOS and it seemed to go through o.k. but then I got that LED. Hopefully I didn't kill the BIOS chips or something, this was just the latest retail BIOS, nothing fancy.
