[soccerdude21490]

Hey everyone well today I started installing Ubuntu and Mac, and everyting installed fine, go to boot into Mac OS X, and the Darwin seems to load fine, and then that Apple Boot up logo comesup and after a few seconds, just dissapears and my monitor(s) go "inactive"

 

I can post more details if needed, just tell me how!

 

BTW: I'm using JaS.Mac.OS.X.10.4.8.AMD.Intel.SSE2.SSE3.PPF.1.Defiant.diskut on an Intel P4 with only SSE2, but I applied the Intel Patch as well as another 2 of them
