Apple MacBook A1534 820-00244 Bios

BIOS image for the Apple MacBook A1534 with logic board 820-00244, stored in a 3.86 MB RAR archive. Apple numbers its logic boards in the 820-xxxxx format, so check that the code on the PCB matches before relying on this dump. Technicians typically program it into the boot ROM SPI flash with an external programmer when the machine does not power on properly or the firmware is damaged. Read and save the existing chip contents first, as they carry the serial and machine identity, and confirm the size suits the chip.
