BIOS package for the Gigabyte GA-B75M-D3H micro-ATX desktop motherboard, PCB revision 1.2, compressed as an 8.55 MB RAR file. It serves to restore a corrupted BIOS flash when the board fails to post or the dual BIOS recovery does not work. Write it with an SPI programmer after extraction. Gigabyte revisions can differ, so match the revision silkscreen, back up the existing chip contents, and make sure the image size corresponds to the flash chip fitted on the board.
