Zip file of 347 KB labelled 945GFBAL1, apparently a desktop board based on the Intel 945 chipset family. The name carries no revision, vendor or document type, so the contents need inspection. A package this small for a 945 era board is consistent with a BIOS image sized for a 4 Mbit or similar flash chip, often in a socketed or SOIC package. Before programming, compare the dump size with the chip capacity, save the original firmware, and make sure the board marking matches the file name exactly.
