Firmware image for HP 15 machines using the Quanta DAG35DMBAD0 mainboard, revision D, board ID 0825F, with ME noted in the name, in a 5.21 MB ZIP. This is one of a set of dumps for the same PCB that differ by board ID, which HP uses to mark hardware variants. Confirm the ID of the unit on the bench before use. Program the dump into the BIOS flash with an external programmer, backing up the existing contents first and checking that the image fits the chip exactly.
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.
