@s00senka Pretty much i just Disabled the ME Firmware (which others said/in other word, “HAP Bit set”), oh but also i used ME 11.8.97.4739 corporate cut version (from 11.8.97.4739 RGN found in this forum, cut down using @dsanke’s me_cleaner fork based on the instruction here), so it’s good to hear that it boots on your side. You can dump your bios after the bios i gave was flashed, and open it in Coffeetime, you’ll see what version of the ME FW it is.
As an additional info, i added Coffeelake and Coffeelake Refresh CPU (and Adjusted the FIT Table), so i guess you can use Normal Retail/Xeon CFL/CFL-R CPUs, or Mutant CPUs such as QTJ1, QTJ2, etc. (since ME FW is disabled, CFL/CFL-R Xeons/Mutant BGA 1440 cpus is doable). I Also inserted RebarUefi and NvStrapsRebar for resizable bar purpose, if you ever plan to use it, you can try to enable Above 4G Decoding in the bios, then refer to this post on how to enable rebar function.
BTW, did you flash it using CH341A/Similiar Programmer, or software like Intel FPT/Flashrom?
