    Hi all,

    I'm new to this forum, but I'm hackintoshing for about 2 years now. In my G5 Casemod, I have a P55M-UD2, Core i3 530 @ 3.3 Ghz, Nvidia 9400 GT 512 MB and 4 Gigs of RAM. Everything installed fine with iBoot Supported + Snow Leopard 10.6.3 Retail DVD. The first time I tried to boot from the DVD, I got a blank screen, so I used -x -v and everything was working. When the installation is completed, and I want to boot my HDD from the iBoot Supported disc, I get a blank screen after the Apple logo, even with -x -v. The Computer just boots from the HDD, and when OS X is booted, I get the blank screen.

    I hope you guys can help me out!

    Thanks

    The Command line switchs that are used after you boot form iBoot may need some expansion.

    Most likely if you didnt use the GraphicsEnabler=Yes option this is the problem.

    As for install from iBoot to OSX Retail DVD - once you have made the swap - and you see the DVD on the screen - you should use a more detailed Command Line string
    this is mine - -x -v -f acpi=off PCRootUID=1 GraphicsEnabler=yes ncpi=0x2000
    I know this is overkill but its what I have used to first start w the install - after you have done the HFS disk prep and waited the 30 min for the Apple OSX to install - and you are to reboot w iBoot again - I use a shorter one

    -x -v -f PCIRootUID=1 GraphicsEnabler=1

    Suggest you look at these pages for explations on starup swithes -
