Firmware dump for the Apple MacBook Pro Unibody A1297, the 17-inch model, with logic board 820-2610, revision A. The 1.37 MB RAR likely holds the EFI boot ROM image used to recover a board that will not chime or start after corruption, written with an SPI programmer. Apple uses the 820-xxxx number with a revision letter for logic boards. Check the number printed on the board, read the original chip first to keep the serial and system data, and confirm the file size matches the flash chip.
