Packed as a 2.10 MB ZIP, this archive belongs to MSI motherboard MS-6737. No further detail is in the name, so the document type, revision and any firmware version are unknown until it is unpacked. Match the MS-6737 code and revision printed on the PCB before relying on what is inside. Schematic PDFs help track down power rail faults and shorted components, while BIOS images are flashed with a programmer. Read and store the existing chip first and make sure the file size equals the chip capacity.
