RAR archive containing the Intel Flash Image Tool at build 7.1.13.1088 from the ME 7.1 system tools. FIT allows a full SPI dump to be opened, its regions checked, and a new image created with a clean Management Engine region for 6-series chipset boards. The rebuilt binary is then flashed with a hardware programmer. Using a FIT branch different from the dump's ME version may fail, so check the firmware version first, and always back up the original chip contents before any write.
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.
