Description
BIOS dump for the Apple A1226 laptop, board number 820-2101, supplied as a 7Z archive of about 1.3 MB. The original file name references the board revision A and an M75 platform with a T7700 CPU, though those details come from the file name rather than a verified spec sheet. A dump like this is used to reprogram the SPI flash chip with a programmer after BIOS 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.
The catalog also lists 1 schematic, 2 boardview files, and 2 BIOS dumps for board 820-2101.

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 A1226 820-2101. 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.
