Intel Flash Image Tool at release 8.1.10.1286, packed in a RAR archive of about 1.01 MB. Belonging to the ME 8 system tools, FIT is used to import an existing BIOS dump, examine its descriptor, ME and BIOS regions, and output a regenerated image with a fresh Management Engine region. Repair technicians apply it for ME cleaning before SPI programming. Check the ME version of the board first so the tool branch matches, and always keep a full backup of the original chip.
