EFI BIOS archive for the Apple MacBook Air 11-inch A1465 on logic board 820-3208-A. Apple marks its boards with 820-xxxx numbers, and the suffix letter indicates the board revision. The image is meant for reprogramming the SPI flash with a hardware programmer to recover a board that fails to boot or shows firmware corruption. Read and save the original contents before writing, since they hold serial and configuration data, and check that the image size matches the chip.
