BIOS firmware for the Compaq CQ61-420ER notebook on the DA0OP8MB6D1 motherboard, supplied as a 929 KB ZIP archive. The DA0 prefix with an MB6D1 ending follows the Quanta scheme, so the board comes from Quanta, built for HP. The image is used to rewrite the SPI BIOS chip with a programmer when the laptop powers up without display or has damaged firmware. Check the board number on the PCB, back up the existing chip, and confirm the extracted image size matches the flash capacity before writing.
