big sur 11.6 Help - Big Sur 11.6, stuck on PCI configuration begin

[BlueBoy31]

Hi guys, new to the forum and opencore, been trying to install Big Sur 11.6 using Opencore 0.7.4 for the past week or so and cannot figure out what I am doing wrong, I just keep getting stuck at [PCI configuration begin] I’ve looked through the guides but cannot figure out, (I’ve tried npci=0x2000 and npci=0x3000 - but no change) some help would be greatly appreciated.

It’s an HP Z840, with the following basic specs:

CPU: Intel Xeon Processor E5-2643 v3

Chipset: C612 Haswell EP

GPU: AMD Radeon RX 5700 XT

Network: Intel I210

Audio: Realtek ALC221

 

I also tried the Monterey beta, but same result.

I’ve attached the config.plist, DSDT dump, the aida64 system report file, the error logs and screenshot of the EFI folder structure.

I’ve tried some of the EFI files on the forum but no luck, If someone could take a look at my files if it’s something I’ve missed or doing wrong.

 

Thanks in advance,

Bob.
