Archive with BIOS for the Gigabyte GA-G31M-ES2L desktop motherboard, labelled dual BIOS and confirmed working. Gigabyte boards with DualBIOS carry a main and a backup flash chip, so the package may cover both. Unpack it with WinRAR or 7-Zip and identify which image goes to which chip. Write with a hardware programmer when the board fails to POST, after saving the existing contents, and check the board revision printed on the PCB since several exist.
