BIOS firmware for a board labelled PN C46 MB NPB, revision E per the VERE token, packed in a 1.53 MB RAR archive. The name gives no brand, so match the silkscreen markings on the motherboard before use. Such an image serves to recover a board with corrupted firmware by programming the SPI flash chip directly with a hardware programmer. Read and store the existing chip contents before writing, and confirm the dump length equals the capacity of the fitted flash IC.
