Apple firmware dump from an A2289 MacBook Pro, logic board 820-01987 revision 06, read from the chip at position U2890. The file is 1.00 MB, so it should be written only to a flash chip of that capacity at the same location. Dumps like this help restore a damaged or replaced chip on a board that fails to power up properly. Read and save the original chip before writing, as Apple firmware often stores machine data, and confirm the board number and chip designator on the PCB.
