No screen after installing Lion on a Latitude E5520 ?


Recommended Posts

So I've tried I don't know how many different ways it I'm getting closer to getting some osx glory on my dell e5520 latitude laptop. There is basically no documentation for this laptop on the Internet so I'm trying to figure out what works based on similar units I see on forums and what not.


The relevant specs for this laptop are: Intel® Core i7-2620M CPU @ 2.70GHz Display Adapters Intel® HD Graphics Family 1804.466796875Mb Intel HD GMA 3000


Right now I'm trying to install with iFail L2. I installed with these options:


chimera (chameleon, stolen and rebranded), Graphics Enabler, FakeSMC,Disabler, RTC, EvOreboot,IOPCI Family,PS/2,Voodoo HDA


Basically, I took the advice given in this thread which was the most similar laptop i could find to my own:



What's Wrong:

The install finishes without issue, but when I try to reboot, when I get to the point where I should see the OS, I get the apple audio helper instead only. The screen stays stuck on the last image of the verbose loader. So I can navigate with the help of the system assistant, but I can't see!


I have tried all different combinations of boot options and nothing works. What can I do?!?
