BIOS and EC firmware set for the Quanta-made board DA0N73MB6D0, revision D, also referred to as N73-D. The name states an 8MB BIOS image, and the files come in a 4.18 MB ZIP. The DA0 prefix is Quanta's laptop board numbering pattern, so the board can sit in a notebook of another brand. Write the BIOS to the SPI chip with a programmer such as a CH341A, and flash the EC image only where the EC uses separate storage. Read and back up the original chip first and confirm its capacity matches 8MB.
