These both are the only ones that I have tried, but I have a Intel P45 Chipset and the MOBO is a ASUS Maximus Formula II. But anyway when I go to boot up the DVD, as it is loading Darwin x86, my screen goes black and my PC restarts. I have no idea why. I know both of the DVD boot up cause i tried them on my laptop which is currently running iDeneb 10.5.5.
