Firmware archive for the Gigabyte GA-945GM-S2 desktop motherboard, revision 3.x. The 945GM in the model name refers to the Intel 945 chipset family that the board is built around. Gigabyte often changes BIOS images between PCB revisions, so the revision silkscreened on the board must read 3.x before this file is used. A technician can program the BIOS chip with an external programmer to recover a board after a failed update. Back up the existing contents and check that the image size matches the chip.
