BIOS firmware package for the Gigabyte GA-945GZM-S2 desktop board, 389 KB in RAR form. No PCB revision is mentioned, which matters because Gigabyte released this model in several revisions with differing firmware. The board is based on Intel's 945GZ chipset for socket LGA775. Use the image to restore a board with corrupted firmware through an external programmer or the vendor flashing utility. Read and save the original chip first, and check that the image size matches the flash capacity.
