Can't boot Lion - [PCI Configuration Begin] fixes not working

Question

My Hackintosh on Lion has been working fine for months.... Then for no reason (I hadn't updated anything) I suddenly can't boot. I used boot flags to find the stall on [PCI Cofiguration Begin] so tried all boot flag fixes.

npci=0x2000 and npci=0x3000 don't help. When I try pci=off it gets past [pci config begin] but stalls shortly after on this...

Smc::smcReadKeyAction ERROR $num kSMCKeyNotFound(0x84) fkeyhashtable=0x0

Previous shutdown cause: 3

Smc::smcinithelper error: MMIO regMap == NULL - fall back to old smc mode

Console 1024 x 768 @ 0xf7000000

I've tried every boot flag I can find and not sure what else to do. It won't start in any mode. Sometimes hangs forever, sometimes just switches off.

I have windows on a seperate HDD in the same system and that is booting fine, so I am certainty not a hardware failure.

Any suggestions or ideas? I didn't build this hackintosh, I bought it, so not sure of set up but it's been working fine for the best part of a year. It was on snow leopard but I upgraded to Lion following the online tutorials. I've been on Lion since its release with no previous problems until this.

I don't have a Lion disc... I do have a SL disc.

Thanks for your help.

Steve

USE THIS COMMAND via Terminal:

bdmesg | grep PCI-Root-UID

Terminal will say:

Using PCI-Root-UID value: X

Take that result and use as below.

PCIRootUID=1 npci=0x2000

PCIRootUID=1 npci=0x3000

OR

PCIRootUID=0 npci=0x2000

PCIRootUID=0 npci=0x3000

It may help since npci by itself is not working, It worked for me. I have even heard of adding:

UseKernelCache=No with the above combos.

If all else fails use:

PCI Configuration Begin Fix - Downloads - OSx86.net

It is yet another remake from snow, I cant recommend it really as it is 10.6.x based. Others have said it works, I just prefer adding flags to my boot plist. I have my Chameleon setup on my EFI Partition, that way it is safe in the event of format, etc. (Basically Read Only as if done correct it is never mounted or visible)

add another flag,command, kext link
