Acer BIOS backup archive for a laptop built on the Quanta board DA0ZHXMB6C0, labelled only as an old backup in a 3.34 MB zip. The name gives no model, BIOS version or chip details, so open the archive and inspect the image size before use. DA0 prefixes with an MB suffix follow Quanta's numbering for main boards, which Acer sources from that ODM. Confirm the number and revision silkscreened on the PCB, read and save the existing SPI chip with a programmer, and check that the dump size matches the flash capacity 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 @afssolutions. Enginerys does not host this file.
