Description
BIOS dump for the Apple A1278 laptop, board number 820-3115, distributed as a 4.0 MB RAR archive. The uploader marked the file as tested, though that label comes from the original post and has not been independently verified here. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after corruption or a failed update. Confirm that the board number and revision on your logic board match before flashing, and back up the original chip contents first so you can restore them if something goes wrong.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: Apple A1278 820-3115. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
