Intel ME firmware 11.8.77.3664 in Consumer form for H-series PCH, DA stepping code, production signed, delivered as a clean RGN region of 1.94 MB. It is part of the CSME 11.8 branch and suits rebuilding an ME region on compatible consumer boards. Before using it, read the existing flash with a programmer, identify the current firmware version with ME Analyzer, and confirm the consumer SKU. The region is then combined with the BIOS in Intel FIT rather than written to the chip on its own.
