BIOS archive for Quanta board DAG3MMB1AC0, revision C, with a 16 MB image indicated for a 128 Mbit SPI flash. Quanta labels its motherboards with DA-prefixed codes like this, and the trailing characters encode the revision, so the laptop brand is not stated here. Use it to recover a board with corrupted firmware. Compare the full code and revision on your PCB, save the original chip contents with a programmer, and check the image size equals the chip before writing.
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.
