Currently I am studying this step-by-step and it is apparently the most important step that scares me, step number 5. I actually haven't even read past that step because after clicking the link there I got pretty lost. I dunno what MOBO on that list is one I can compare to. I have never heard of a .kext file, so I stopped there, for now.
I am hoping to install the latest or best fit version of OSX to fit my build. I suppose it is hard to tell without trial and error, but from what I've seen/read it will probably be iPC or Snow Leopard.
P.S. I was also hoping to get a startup or bootup interface that looks like or is similar to this.
