Where did you get ADR=0x03 for PCI1 ?
03 is in "ADR Device (QR3A)".

Oh! I may have made a mistake by reading Windows "PCIROOT(A0)#PCI(0300)#PCI(0000)" the same way as PCI path "PciRoot(0xA0)/Pci(0x3,0x0)/Pci(0x0,0x0)" as could be used by OpenCore.

Which then raises two questions. Is the address of PCI1 0xA0? I've never seen an address so high!

And, purely out of curiosity, if "PCIROOT" in Windows is the first object under the PCI root, how does Windows deals with and reports multiple PCI roots?

 

@shamann Here are two alternative versions of SSDT-PCIA with addresses 0x00 and 0xA0 which you may try.

As he writes, the patch with "ADR"=0x00 works but crookedly. Therefore, SSDT with "ADR"=00 will not work. He needs to try to change "ADR" to another value. Perhaps your SSDT with 0xA0 is working. And in the patch in “Replace” it should look like this, the last digits “00A0”. There is a possibility that you were also right with “3”; if you look at the CPU2 index, it is equal to 0x30. Then the value should probably be "0030" in the patch and 0x30 in the SSDT.
