Flash Image Tool from Intel, version 16.1.25.2091, supplied as a 14.7 MB 7z archive. FITool loads a full BIOS image and lets the user view and edit flash regions, descriptor settings and ME configuration, then generate a new binary. Technicians use it to repair ME corruption or merge a fresh ME region into a dump. Pick this build only for ME 16.1 firmware, confirm the resulting image size matches the flash chip, and keep a backup of the original.
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.
