Windows executable of the Intel Flash Image Tool, build 16.0.15.1662, roughly 14.8 MB in size. MFIT belongs to the CSME 16 family of Intel system tools and lets a repair technician load an SPI flash image, view its descriptor and regions, swap in a clean Management Engine region and save a rebuilt binary. Use it only with platforms whose ME firmware matches the version 16 line, verify the output size equals the flash chip capacity, and keep the original dump safe before programming the chip.
