Intel CSME firmware 16.1.25.1991 packed as a 1.66 MB RAR file. The tokens mark it as a Consumer (CON) image for H-class platforms, with X as the stepping token, a production build (PRD) and an image extracted from a package (EXTR). It is meant for desktop or high-performance H chipset boards rather than LP laptop platforms. Technicians use it with the version 16 Flash Image Tool to rebuild a damaged ME region. Do not mix H and LP images, and always save the original SPI chip first.
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 @laptexlaptopbios. Enginerys does not host this file.
