RAR package with Intel FIT version 8.1.40.1456, a later build from the ME 8.1 Flash Image Tool line. It opens and rebuilds SPI flash images, letting the user replace or clean the Management Engine region and adjust descriptor settings on 7-series chipset boards. This is typically done when a laptop shows ME errors or uses a dump taken from a different unit. Verify that the ME firmware in the dump is from the 8 branch and save the original chip read before flashing the rebuilt image.
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.
