Intel FIT 14.5.25.1229 in a 15.1 MB RAR archive. The 14.5 branch is distinct from the mainstream 14.0 releases, so this Flash Image Tool should be paired only with ME firmware from that same line. Technicians use FIT to open a full SPI dump, inspect its regions, insert a clean ME image, adjust descriptor settings and rebuild a binary for reflashing with a programmer. The archive may include extra CSME utilities. Always keep the original dump and check the rebuilt size against the chip.
