BIOS archive for the 2012 MacBook Air A1466 with an i5 CPU, 4.58 MB in ZIP format, apparently intended for the logic board's EFI flash chip. Because the A1466 model number spans models from 2012 to 2017, read the 820 board number printed on the PCB to make sure it is the 2012 board before writing anything. Use an SPI programmer, keep a backup of the original dump, and confirm that the image size matches the chip capacity, or the write will fail or brick the board.
