Firmware archive for the MacBook Pro A1236 bearing the Apple WHITE ARROW name, packed as a rar of about 1.80 MB. The name gives no logic board number, revision or EFI version, so confirm the board before using it. A dump like this is written to the boot flash with a programmer to recover a machine that powers on but does not start. Read and keep the existing chip contents, which contain the serial, match the 820 number printed on the logic board, and make sure the image size suits the chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
