RAR archive (6.25 MB) labelled as Intel Flash Image Tool 11.0.49.1536. The size and build number are identical to the 12.0.49.1536 archive in this collection, so the label may be a mix-up and the real version should be checked inside before use. FIT reads an SPI image, splits it into regions, lets you edit ME settings and rebuilds the image with a clean Management Engine region for flashing with a programmer. Use the version that matches your ME firmware and keep the original chip dump.
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.
