I can't boot up the installer of Mac OS X Lion.

I have a Dell Latitude D630 with Nvidia Graphics.

It has a Core 2 Duo with Nvidia Quadro 135m

This is what happens when I try to boot up from the USB installer.

I am on step 3. The Unibeast installer will not boot.

You may need to play with the bootflags a bit...

npci=0x3000 or npci=0x2000

and/or

PCIRootUID=1

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

I am having this same issue with my sandy bridge system that has never had any issue booting in the past. I am currently stuck on [PCI configuration begin]

gigabyte H61 USB3
GT 640
i5 2500k

I have tried all combinations of PCIRootUID=0/1 and npci=0x2000/0x3000. In the past all the system needed to boot was PCIRootUID=0 GraphicsEnabler=No npci=0x3000 (lion through mavericks). kext-dev-mode=1 and IGPEnabler=Yes both seem new to this round of MB. I have tried their revereses as well in the boot flags with no success. Would love love love some help here. I feel like I am really close, would much prefer to have yosemite on this system then reverting back to mavericks for the long run.

UPDATE:
ACPIPlatform rollback gets the status bar going, but I have to enter in npci=0x3000 PCIRootUID=0 as flags. I thought that I would then add those to my kernal flags within the p-list but even when I do that I get a black screen with stuck status bar on the bottom left hand corner. I am adding the flags in the same string as the kext-dev-mode=1 is currently located. Also, I am not getting any sound even though I have added the ALC889 kext via MB. Going to keep working on this, but what a pain in the ass!!
