RAR archive holding Intel Flash Image Tool (FIT) build 9.0.10.1372, part of the Management Engine 9.0 system tools used on 8-series chipset platforms. FIT lets a technician open a full SPI image, inspect the descriptor, BIOS, ME and GbE regions, adjust straps and rebuild a clean image. The ME tool version should match the ME firmware family in the dump being edited, otherwise the image may not parse correctly. Always keep a backup of the original chip contents before writing any rebuilt image with a programmer.
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.
