BIOS binary for an Acer laptop using the Quanta DA0Z09MBAHO motherboard, revision H, in a 1.06 MB ZIP. Quanta identifies its boards with the DA0 prefix and MB marker seen here. The image is meant for writing to the SPI BIOS chip with a programmer when the system shows no display or is stuck after a bad update. The EC firmware for this board is a separate file. Verify the board revision, back up the original chip, and check the image size matches the flash.
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.
