Intel Flash Image Tool, MFIT version 16.1.25.2091, packaged as a 13.2 MB Windows executable. MFIT is part of the Intel CSME System Tools kit and is used to open, inspect and rebuild full SPI images, including the flash descriptor, ME region and BIOS region. Technicians use it to unpack a dump, replace or clean the ME region and generate a new image for a programmer. Match the tool generation to the platform's ME firmware version, and always keep a backup of the original chip contents before writing anything rebuilt.
