Working BIOS for the Microsoft Surface Pro 7+, marked MP5 W mainboard, in a 5.75 MB RAR archive. The MP5 W token appears to describe a board variant but its precise meaning is not stated. Surface firmware sits on an SPI flash on a compact, densely packed logic board, so careful handling is needed when clipping or removing the chip. Extract the image, confirm it matches the chip capacity, and take a full backup of the original flash before writing anything with a programmer.

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 →
