Quanta DA0ZHJMB6E0 mainboard firmware, revision E, project code ZHJ, supplied as a 2.69 MB RAR. The DA0xxxMBxxx format is Quanta's ODM board numbering, so the laptop brand is not indicated by the name. Repair shops use such dumps to recover boards with corrupted BIOS by writing the SPI flash directly with a programmer like a CH341A or similar. Save the original chip contents before programming, compare the board number and revision E printed on the PCB, and check the dump size against the flash chip capacity.
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.
