Firmware dump attributed to Microsoft, labelled with the part code M1098028-006, which looks like a Microsoft board or assembly identifier; the name gives no product model. The raw binary is 16.0 MB, matching a 128 Mbit SPI flash chip. Before programming, read and save the original chip contents with a programmer such as a CH341A or RT809, confirm the chip capacity equals the image size, and check that the code printed on the board matches the one in the name so you do not flash firmware from a different Surface or device revision.
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 @zinfoservicebios. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
