Archive for the HP Pro C640 Chromebook built on Quanta board DA00GCMBAE0, revision E, with the name referring to Windows 10, likely firmware for running Windows instead of ChromeOS. Size is about 8.37 MB in RAR form, and the exact contents should be checked after extraction. DA-prefixed numbers ending in MB6E0 or similar follow the Quanta ODM pattern used in many HP machines. Before writing any firmware, confirm the board number and revision E on the PCB, read and save the original SPI chip, and verify the image matches the flash capacity.
