Raw firmware binary in a ZIP for the MacBook Air A1466, 2012 model with a Core i5 processor. Images like this are written to the EFI SPI flash with an external programmer to revive a logic board with damaged firmware or to replace a locked one. The name gives no board number, so confirm the logic board part number on the PCB matches a 2012 A1466. Keep a full read of the original chip, since it holds the serial and other machine-specific data.
