@kgp feel free to correct me anywhere but PC02-BR2A is typically slot-1 which is where the gpu usually is placed in most systems. The issue that makes the Sage boards more complex is that it uses a pair of plx chips which results in all of these pci-bridges. Was very difficult for me to adapt to when I was first learning but all I was missing was a couple of lines to differentiate which device was under what pci-bridge. Like @kgp said, it's definitely more demanding than other boards but is a lot easier once you get the hang of it
I believe PC02-BR2A covers slots 1,3 and PC01-BR1A covers slots 5,7 though I'm not 100% on that. I have no idea where slots 2,4,6 show up under since I haven't tried putting something in there yet. My guess is another pci-bridge will populate and it will shuffle the locations around. Thunderbolt under slot-2 actually shows up under the PCH.
Here are some examples:
Slot-1: PC02-BR2A-Pci Bridge 10
Slot-3: PC02-BR2A Pci Bridge 8
Slot-7: PC01-BR1 Pci Bridge 8
It definitely will make a lot more sense once you have ioreg and are able to look at it besides the SSDT code. Good luck!
Very interesting! It seems then, if I understood correctly, that you have your NVIDIA card in slot 1 and the Vega Frontier Edition in slot 5 while your airport card is in slot 7. So to have a graphics card in slot 1 and 3 I would need to reference the same PC02-BR2A and just specify the "Slot-X" in AAPL,slot-name?
