BIOS archive for an ESONIC G31GCCFL2 desktop motherboard, model code M131C, revision 4.1, built on the Intel G31 chipset as the board name indicates. The RAR file is 513 KB, consistent with the small flash chips used on boards of that era. It can be used to recover a board with a corrupted BIOS by writing the image with a programmer. Confirm that the board revision matches 4.1, verify chip capacity against the extracted file and keep a copy of the original contents.</p>
