RAR archive with BIOS firmware for revision 1.0 of the Gigabyte GA-B75M-D3H motherboard, about 8.55 MB. A dump like this is used to repair a board with corrupted firmware, either through an SPI programmer clipped onto the chip or a reflash after desoldering. Gigabyte often lists several revisions of one model, so check the marking near the expansion slots. Back up the current chip contents before writing, and verify that the extracted image size matches the flash part on the board.
