Dump for the Apple A2337 MacBook Air with board 820-02016-A, read from component UF260, provided in a 222 KB RAR. The A2337 is an Apple silicon model, so its flash layout differs from older Intel Macs with an EFI SPI chip. Apple uses 820-xxxxx board numbers with a revision letter. Technicians use such files to restore a corrupted small serial flash after board-level repair. Back up the existing chip, match the designator and board number exactly, and use a programmer that supports the part.
