How to definetly fix pci configuration error

[ctroncosor]

1- Ok first you need to EFI inject your videocard, for that you can take the rom with NVCAP Maker and use OS X 86 Tools to make the efi string.

2- Once you have done that install this 2 kexts with kext wizzard:

Gringo Vermelho posted a DSDT fix for 10.6.8 that may work in Lion. I haven't tested it myself because I didn't have this issue, but other people confirmed it works

Just replace _ADR by _UID in device PCI0.

Before:

Device (PCI0)
{
Name (_HID, EisaId ("PNP0A08"))
Name (_CID, EisaId ("PNP0A03"))
[color=#FF0000]Name (_ADR, Zero)[/color]
Name (_BBN, Zero)
OperationRegion (HBUS, PCI_Config, 0x40, 0xC0)
Field (HBUS, DWordAcc, NoLock, Preserve)

 

After:

Device (PCI0)
{
Name (_HID, EisaId ("PNP0A08"))
Name (_CID, EisaId ("PNP0A03"))
[color=#FF0000]Name (_UID, Zero)[/color]
Name (_BBN, Zero)
OperationRegion (HBUS, PCI_Config, 0x40, 0xC0)
Field (HBUS, DWordAcc, NoLock, Preserve)
