BIOS dump for the Quanta R53 board, numbered DA0R53MB6E0 at revision E, supplied as a 2.28 MB ZIP. Quanta, a large notebook ODM, prints DA0xxxMB codes on its mainboards, and the project code R53 is embedded in this number. Read the existing SPI chip with a programmer and keep the copy before writing. Compare the image size with the chip capacity, and check that the PCB marking and revision E match, since other revisions can use different firmware.
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.
