BIOS set for the Quanta motherboard DA0WJBMB6C0, revision C, project code JWB, holding images for a 1 MB and an 8 MB chip, in a 3.1 MB RAR archive. Boards like this use two SPI chips, the smaller usually holding EC firmware and the larger the system BIOS. The name does not state the laptop model. The DA0 prefix with an MB suffix is Quanta's board numbering. Match each image to the correct chip capacity, back up the original contents, and confirm revision C on the PCB before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
