BIOS dump for the Quanta board DA0U83MB6E0, revision E, with the Intel Management Engine region cleared, supplied in a 3.79 MB RAR archive. Quanta uses the DA0 prefix pattern and this U83 board is found in the HP ProBook 440 G1 and similar models. A clean ME image helps fix boards that hang, power-cycle or run the fan at full speed. Check the revision on the PCB, back up the original SPI contents with a programmer, and confirm the image size matches the chip before writing.
