Area 51 Desktop: Revert to Older BIOS?
I just had my motherboard replaced. I had been having 2 problems: 1) With SLI enabled with my nVidia GTX 460's and USB2 peripherals plugged in, on starting up I would end up with VGI resolution. 2) With XMP memory installed, when accessing the DIMM2 readings in the BIOS v.A09, either the computer would freeze, or I would get a "Multi-Bit ECC ERROR" even though the memory is non-ECC DDR3 XMP.
On the old motherboard, I had BIOS v. A09. When the new motherboard was put in, with BIOS A05, neither of the 2 problems showed up, and the computer ran fine. I flashed the BIOS to A09, and now both the problems are back.
Is there a way to get a copy of the A05 BIOS, and is it possible to install it over the A09 again?
I don't know about finding A05 but here is a good tutorial on how to " backflash " using USB stick or temp partition on C drive if you can't within windows.

The older ones are here but not A05. I have never tried to backflash. Maybe another user has saved it and can upload it?
