Clean BIOS image for the HP Chromebook C640, built on Quanta board DA00GCMBAE0 at revision E, sized at 16.0 MB. A clean dump normally means personal data or serial details have been cleared so the image can be written to another unit, which is useful when firmware is corrupted and the machine will not boot. Quanta numbers starting with DA0 identify the ODM layout, so check the PCB silkscreen and revision. Read and save the existing SPI contents with a programmer first, and confirm the chip capacity matches the 16 MB file.
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 @bios_laptopomi. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
