Boot ROM dump for an Apple MacBook Pro using logic board 820-2101, revision A, supplied as a 1.11 MB RAR. The name does not mention the model number or year, so match the board number silkscreened on the PCB before use. Technicians write such images to the SPI flash with a programmer to revive machines that fail to boot because of corrupted EFI firmware. Read and archive the original contents first so serial and system data can be restored, and verify the image fits the chip capacity.
