BIOS image for the H81M-VG4 desktop motherboard, version 2.01 according to the name, supplied as a 3.00 MB RAR archive. No brand is stated, though the model designation is commonly found on ASRock boards. It suits recovery of a board with a corrupted BIOS by writing the SPI chip with an external programmer. Read the original chip first, check that the image matches the chip capacity, and make sure the board model and revision on the PCB correspond.
