Combined BIOS and EC firmware for motherboard DAG94AMB8D0, revision D, packed in a 4.19 MB RAR. The DA prefix with the MB8D0 ending follows Quanta numbering, so the board is a Quanta design; the laptop brand is not stated. Having both images lets a technician restore the main SPI flash and the keyboard controller firmware when a unit will not power on or charge properly. Check the board code and revision printed on the PCB, back up both chips before writing, and verify that each image size matches its chip.
