Intel FIT, version 14.0.11.1205, in a 6.33 MB RAR file. The Flash Image Tool is Intel's utility for building SPI images from descriptor, ME, BIOS and other regions, and for editing platform settings inside them. Technicians typically load a dump read from the board, swap in a fresh ME region and save a clean image. It suits firmware in the 14.0 family. Different FIT releases are tied to specific ME versions, so verify the match first, and keep an original backup of the flash chip before any write.
