BIOS image for the Quanta board DA0X3CMBAF0, revision F, packed in a 13.6 MB RAR. The DA0 prefix is Quanta's numbering pattern, used on boards for several laptop brands, and the brand is not stated here. The archive contents beyond the BIOS are not listed. Before reprogramming the SPI chip with a flash programmer, read and keep a backup of the original, confirm the PCB shows DA0X3CMBAF0 rev F, and make sure the dump size matches the chip capacity.
