Clean-ME BIOS dump for the Apple A1708 MacBook Pro, EMC 3164, on logic board 820-00840-A. The raw binary is 8 MB, matching the board's SPI flash. Technicians write such an image with an external programmer when firmware corruption prevents boot, or when the ME region must be reset. Since the EMC differs from other dumps for the same board, confirm both the EMC and the 820- number. Save the original chip first so the serial number and hardware data can be moved into the new image.
