Lenovo A720 all-in-one main BIOS for Quanta board DA0QU7MB8C0, revision E, provided as a 2.00 MB binary file. The DA0 prefix indicates Quanta manufactured the board for Lenovo. The image suits a 16 Mbit SPI chip and is written with a programmer when the system shows no video or fails after a bad update. The board also carries keyboard controller firmware in a separate image. Check that the revision printed on the PCB matches, and read and store the existing contents before erasing.
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 @abgm_manutencao_bios. Enginerys does not host this file.
