EFI firmware package for the Apple MacBook Air A1466 from 2012 with a Core i5 processor, 4.58 MB compressed. It is used to reflash the logic board's SPI ROM when a corrupted image prevents booting or a firmware lock needs clearing. Neither the 820 logic board number nor the EMC code appears in the name, so check the board before use, since A1466 covers several generations. Dump and save the original chip contents first and verify that the image size fits the installed flash.
