BIOS file for the Gigabyte GA-945GCMX-S2 desktop motherboard, revision 6.6, packed as a 379 KB RAR. Gigabyte prints the board revision on the PCB near the expansion slots, and it should match 6.6 before you program this image. Technicians use such a file to recover a board with a corrupted BIOS by writing it to the flash chip with a programmer. Read and keep the existing contents first, and check that the image size suits the flash chip capacity.
