BIOS file for the Gigabyte GA-970A-UD3 desktop motherboard, revision 3.0, sized for a 4 MB flash chip. It is useful when the board fails to POST after a bad update or a corrupted chip, and can be written to the SPI BIOS with an external programmer. Gigabyte boards of this class often use DualBIOS, so confirm which chip is faulty. Verify the PCB revision is 3.0, back up the existing contents, and confirm the image is exactly 4 MB before programming.
