ZIP archive of 462 KB containing G41MM221.BSS, which points to a BIOS for an Intel G41-based desktop board. The name carries no brand, board number or revision, so identify the motherboard model printed on the PCB before use.

Save the original chip contents first and verify the image matches the chip capacity.
