Lenovo BIOS dump for Quanta board DALVACMB8D0, revision D, with the Intel Management Engine region cleaned, 16.0 MB with no file extension. A cleaned ME region resets the engine to a fresh state, which helps with ME corruption faults that cause boot or power issues. DA...MB... numbering identifies Quanta boards. Write it to a 16 MB SPI chip with a programmer, after saving the original contents, and confirm the board marking and revision D on the PCB before use.
