Black Screen Before OSX Installation

Here are the steps I took before I encountered the black screen.

Changed my bio settings to Achi mode
Booted with iboot 2.5.2
Took out the iboot cd and inserted osx 10.6.3 disc after the promt
Pressed f5 and then enter

Apple logo displayed on the screen for a while, and then I got a black screen. I waited like 10 minutes to see if it's still loading, but nothing happens. Does anyone know what would be the problem? I'd really appreciate if anyone can help me.
Thanks,

You need to use iBoot-GE and then install the NVIDIA updated driver
