ZIP of roughly 14 MB carrying Intel FIT 16.50.0.1120, the Flash Image Tool for the CSME 16.50 firmware family. It is used to open a BIOS dump, view the region map, replace or regenerate the Management Engine region and output a complete SPI image. That workflow fixes boards whose ME data is corrupted or copied from another unit. Confirm the platform actually runs ME 16.50 before using this build, keep the original dump as a backup and verify the image size against 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.
