I have a retail installation running. Updated all the way to 10.5.7. The only problem is that I need to boot it with "cpus=1" or it crashes. Would setting up DSDT help to alleviate this problem? Or is there something I forgot to do that's causing this?

On a different partition, I run an installation of iATKOS 5i with the Voodoo kernel installed and I can boot that without "cpus=1" but that's a modified kernel.

My specs are in my signature.

Thanks in advance.
