Intel FIT release 7.1.20.1119 in a RAR archive, part of the ME 7.1 Flash Image Tool series. Technicians use it to load a stock flash image, inspect or change Management Engine and descriptor parameters, and generate a corrected full image for an SPI programmer. It is particularly handy when an ME region has been corrupted or copied from another machine. Confirm the ME firmware branch of the board matches this tool, and keep an untouched backup of the chip before programming the new image.
