BIOS file for the Gigabyte GA-870A-UD3 desktop motherboard, revision 2.0, based on the AMD 870 chipset. Gigabyte revisions can use different flash chips and firmware, so check that the rev 2.0 marking on the PCB matches before use. The image can be programmed into the SPI chip with an external programmer to recover a board that fails to POST, including on a DualBIOS setup. Save the existing contents first and check that the file size equals the chip capacity.
