Intel Management Engine 11.8.77.3664, Corporate build for H-series PCH with DA stepping code, signed for production and packaged as a clean RGN region of 7.01 MB. Such stock images are the preferred starting point for building a fresh ME region because they carry no prior machine configuration. Use ME Analyzer to confirm the version and SKU of the board's own firmware first, then integrate the image with Intel FIT. Writing a mismatched SKU can leave the ME non-functional, so keep the original dump on hand.
