BIOS image for a Microsoft Surface Pro 5 with logic board M1007506-015 and an Intel Core i5-7267 processor. The name marks the dump as working. It comes as a 3.54 MB RAR archive, so extract it and check the actual image size against the SPI flash before programming. Surface boards are compact and the flash chip is often hard to reach, so a careful clip or chip-off read of the original firmware is strongly recommended. Keep that backup, since it may hold device-specific data that a generic dump lacks.
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.
