Firmware dump for the Microsoft Surface Pro 7, the model based on 10th-generation Intel Core, with model number 1866. The name marks it as tested and working, which is a useful sign but not a guarantee. The 4.65 MB RAR should hold an image for the SPI flash on the logic board, used to recover a tablet with corrupted UEFI firmware. Surface boards are compact, so plan the chip access or clip connection in advance. Dump the original contents before programming and check the image size against the chip capacity.
