Zip archive of 17.4 MB labelled Mfit 21, filed as a BIOS and firmware utility. MFIT is the name used for Intel's Flash Image Tool, and the number 21 suggests the build for ME version 21, though the name gives no exact build. The tool opens full SPI dumps, shows the descriptor, ME and BIOS regions, and rebuilds a clean ME region for a new image. Make sure the tool version matches the ME firmware on the target board, and keep a backup of the original chip before flashing.
