BIOS archive for the Gigabyte GA-P31-S3G desktop motherboard, an Intel P31 chipset board, packed as a 736 KB RAR. The name gives no BIOS version or PCB revision, so compare the revision printed near the PCI slots before use. Gigabyte boards of this generation often carry DualBIOS chips. A raw image can be written to the SPI flash with a programmer when Q-Flash recovery fails. Back up the existing chip first and confirm that the file size matches its capacity.
