Thanks for the very fast response! My main problem is that I can't startup into OSX Mountain Lion any more to follow the guide... Can I somehow reset multishit settings or install another DSDT without having to get into OSX? I think I used the wrong DSDT (maybe not even a DSDT, I renamed a txt to aml so might have been a patch). THanks

Hi guys! I really hope you can help me. Its probably simple to solve my problem but I am kind of a newbie and would really appreciate your help. I have the same Asrock z68 Pro3, nvidia 570, and had a working 10.7. OSX on my desktop and tried to update to Mountain Lion. Before doing so I updated my BIOS from an old one to 2.10. After using Ultibeast and installing the Update I was able to startup into Mountain Lion using 'PCIRootUID=0 -F' option. Then I started multishit using a DSDT I dowloaded from the Inet (maybe wrong version, I changed *.txt to *aml ending), ticked some checkboxes I thought would be ok and ran it. But now I can't restart into Mountain Lion any more. Not even using iBoot . What to do? In the posts you are talking about patches. Are these DSDT's or how can I use them for my PC? Thanks for any help!
