I've tried that DVD and it wont even get me to the installation screens. it just reboots my computer soon as it starts loading. i think the last thing it says is "starting Darwin x86". you know when it changes resolutions and starts printing the text in a smaller font. before it switches the screen resolution. it reboots.

I think this is whats i've seen referred to as a kernel panic. but i've tried flags to stop it but none seem to work. if you have some to offer to this then i'm willing to give them a try.
