ZIP archive of roughly 14 MB with FIT 16.0.15.1662, a later build in the Intel CSME 16.0 tools line. The Flash Image Tool opens full SPI images, lets you edit descriptor and ME settings, and outputs a rebuilt binary with a fresh Management Engine region. It is the usual utility for preparing ME clean dumps for boards with ME 16 firmware. Save the original chip contents before modifying, match the tool version to the firmware in the dump and verify the resulting image fits the flash chip.
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.
