Thanks for the excellent guide teamawesome!

I have a question regarding your power management - is XCPM enabled on your hackintosh?

I've been struggling to get it to enable in High Sierra.

No, it is not XCPM. We are using EP chips in multi-processor configuration which makes XCPM a no-go. However, you don't need XCPM for a fully functioning power management. XCPM is just one of the ways Apple has implemented CPU PM. If you follow all the steps in guide, you should have fully functional CPUPM. See Post #9. Unless I am mistaken (it has been a while since I put the guide together, but I did spend a long time researching PM at the time), there is no way to make XCPM work with our configuration.

Appreciate the reply. I was having trouble getting PM to work. I finally managed by flagging every option with ssdtprgen (including logical processors).

I have another question - in your modified bios you mention you unlock the MSRs. Did you follow someone's guide to perform this task?

I'm really struggling to get nvme to boot, even with your modified bioses and the bcfg configuration. Bcfg shows the drive but for whatever reason in the bios boot menu it is simply absent. I had thought about taking a stab at inserting an nvme driver as outlined on the win-raid forums.

Download the original, untouched BIOS from ASRock. It is up to you if you update the CPU microcode or not with UEFI Bios Updater (UBU). Then unlock the MSR with UEFIPatch. Lastly, add the necessary OPROM modules for NVMe boot support.
