BIOS dump that the name associates with the ASUS M1403QA, board revision 2.0, packed as a 5.90 MB RAR archive. No flash size is stated, so check the extracted file against the capacity of the SPI chip on the board before writing. Technicians use such dumps to reprogram a corrupted BIOS chip with an external programmer when a board will not power on or post. Read and save the existing firmware first, and confirm the revision printed on the motherboard is 2.0 to avoid flashing an image meant for a different layout.
