Thank you for your response!

As you can see in pics attached, I am using opencore.efi debug version, and 67 on Target. But I am getting this Access Denied! so I never get to the Opencore boot menu to build a txt file that includes MMIO.

Hello fabiosun,

Trying to get my MMIO Whitelist info for my X870 MSI. When I use the Opencore Release OC 1.0.3 I get to the Opencore boot menu with no issue. Starts to boot but then boot loop as there is no MMIO Whitelist included in the config. So when I use OC 1.0.3 Opencore.efi debug I get the boot menu as in the attached pic, but then a boot loop. I never get to the Opencore boot menu. Any idea?

I found the problem. My mistake. Wrong ethernet kext.

Thanks!

Did you have a boot loop error with this board?  Please see my video.

Thanks!

Tried to boot and get: [EB|#LOG:EXITBS:START]

Maybe your never bios helps. My bios is f4i.

Thank you meina222!

I did disable wake on lan and with the graphics card in slot 1,3,4 it hangs on the desktop. But with the graphics in slot 2 it turns off for 2 seconds, then back on.  I am not quite sure which MMIO's to enable, currently all 14 out of 18 are enabled. The last 4 I removed (skip 0).

Something interesting:

With the Vega 56 in Slot 1,3,4 it will hang on desktop image. In Slot 2 it shutdowns and restarts.

Here is the log.

I also added the ioreg.

Here is my EFI. 

I tried the ethernet setting on both controllers and still no complete shutdown, only reboot.

Thank you!

Thanks to iGPU I was able to get shutdown to work using MMIO whitelist, but now when you shutdown it restarts.
