Raw 8 MB firmware binary for an Apple logic board numbered 820-2915, revision A according to the name. Apple marks its logic boards with 820-xxxx numbers, and this one is commonly fitted to the 13-inch MacBook Pro, though the name gives no model. The image is uncompressed and ready to write to the board's 8 MB SPI flash with a programmer. Before flashing, read the original chip, since serial number and other machine data can be stored in the firmware region, and confirm the board number on the PCB matches.
