Flash Image Tool from Intel, build 11.8.77.3664, in a 5.53 MB RAR archive. Within the ME System Tools family, FIT handles decomposing and rebuilding SPI images: it reads the descriptor, ME and BIOS regions, lets you adjust ME options, and outputs a fresh image with a clean Management Engine region. Boards showing ME faults are commonly repaired this way before reprogramming the flash chip. Version matching matters, so confirm the dump carries 11.8 ME firmware, and never write the chip without a verified backup.
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.
