RAR archive (5.19 MB) containing Intel Flash Image Tool 11.8.86.3877, a late release in the 11.8 branch of the ME System Tools. FIT opens a full SPI image, shows the flash descriptor plus ME and BIOS regions, and rebuilds the image after you replace the ME firmware or change its settings. It is a common step when cleaning ME on boards that power on slowly or report ME errors. Use it only with images whose ME firmware is 11.8, confirm output size equals the flash chip capacity, and back up the original.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @mfittool. Enginerys does not host this file.
