BIOS dump for the Microsoft Surface Pro 5, packed in a 3.91 MB RAR archive. The name does not list the board number, flash chip type or firmware version, so inspect the extracted image and compare it with the chip fitted on the logic board. Technicians use such dumps to recover a unit that fails to boot after corrupted firmware by reprogramming the SPI flash with an external programmer. Read and back up the existing chip first, since device-specific data may live in it, and check that the image size equals the chip capacity.
