ERROR: nVidia ROM Patching Failed!

[Terodon]

Hi

I tried to install Mac OS X Lion on my laptop. I always get this message:
ERROR: dcbtable_version is 0x4
ERROR: nVidia ROM Patching Failed!
After this message the Apple logo screen is shown and the process freezes (like in the image).

I tried two different ways:

1.
I burned a CD with rBoot LE and a DVD with OS X.

2.
I created an Bootable USB Drive with UniBeast.

Do I need to install DSDT? If yes which is the right one for my laptop?

Can anyone help me? Would be great!

I have the same problem.

I created bootable USB with
http://tonymacx86.blogspot.com/2011/10/ ... using.html

Tried boot options:
-PCIRootUID=0
-PCIRootUID=1
-GraphicsEnabler=No
-GraphicsEnabler=Yes

And still wasn't able to even start installation.

Graphic card is nVidia GT 550 with 2GB of memory/

I get these messages upon start up of my working OS X installation. I do not think this is your problem, unless you happen to have an nVidia card

Look for a driver here: http://www.nvidia.com/Download/Find.aspx?lang=en-us

Unpack the pkg and replace the kexts in your USB.

A program called unpkg.

P.S. Try the latest Quadro driver (maybe it works). You wont lose anything, if it doesn't work you still have some Nvidia drivers ready if you need them.
