Firmware archive for Quanta board DA0Y0FMBAH0, project code Y0F, at about 25.7 MB. The DA0 prefix is Quanta's board numbering, and the final characters are the revision. No laptop brand is given, though Quanta builds boards for several makers. The size suggests more than one image, possibly BIOS plus other chips, so check what is inside. Back up the original SPI chip before writing, and make sure each image size matches its flash chip capacity, or it will not fit.
