Firmware archive for a Microsoft Surface Pro on logic board M1007506-015, labelled as working. The name does not give the model generation or CPU, so compare the processor marking before flashing, because this board number appears with different CPU versions. The 3.88 MB RAR has to be extracted and its image size checked against the SPI flash capacity. Technicians use such dumps to recover boards with corrupted BIOS. Read and keep the original chip contents first.
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.
