Firmware package for a Quanta-built laptop motherboard, DAG7HFMB8C0 at revision C, combining a 16 MB BIOS image with EC firmware according to the name. No laptop brand or model is stated, so identify the machine by the board number silkscreened on the PCB. Quanta uses the DA0 or DAx prefix plus a project code for its boards. Unpack the ZIP, compare the image size with the SPI chip markings, back up the existing contents with a programmer, and only then flash the BIOS and EC parts.
