ZIP of roughly 8 MB containing Flash Image Tool version 14.0.60.1790 from Intel's ME system tools. Technicians load a BIOS dump into FIT to review flash regions, change settings and rebuild the image with a new ME region, which is the usual route to an ME clean dump. This release belongs to the 14.0 line, so it suits platforms running ME 14.0 firmware. Read the original SPI chip with a programmer and save it before modifying anything, and check the rebuilt file matches the chip capacity.
