Firmware archive for the Gigabyte GA-P55A-UD3 motherboard, specifically PCB revision 1.0, roughly 1.57 MB compressed as RAR. Repair shops use such a dump to reprogram a corrupted BIOS flash on boards stuck without post or with a failed dual BIOS recovery. Do not mix it with the revision 2.0 image, since Gigabyte sometimes changes hardware between revisions. Confirm the revision marking on the board, back up the existing chip with a programmer, and check that the file size equals the flash capacity.
