BIOS image for the Gigabyte GA-P61-S3 desktop motherboard, revision 2.0, intended for a 4MB flash chip according to the name. Gigabyte boards often carry a main and backup BIOS chip, so identify which device you are reprogramming before starting. The archive is meant for repairing boards that fail to POST because of a damaged firmware region, written via an SPI programmer or clip. Make sure the board revision printed near the PCI slots matches 2.0 and dump the original contents first to preserve onboard settings and MAC data.
