Intel Flash Image Tool at version 15.40.16.2534, supplied as a 6.42 MB RAR archive. The 15.40 branch is a separate firmware line from mainstream 15.0, so this tool should be used only with ME images from that same branch. FIT can open an existing flash dump, show the descriptor and region layout, change straps and settings, and build a new SPI image. It is a standard step when cleaning or restoring ME. Read and archive the original chip with a programmer before writing any modified result.
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 @mfittool. Enginerys does not host this file.
