I tried to boot the snow leopard dvd with the iboot ivy bridge version, but i'm unable to go over the apple logo. I just see the apple logo and then appear the prihibition sign. I tried to write "PCIRootUID=1" or "-x" to go in safe mode but it doesn't work. As well i tried also the GraphicsEnabler=No but nothing, it don't let me go on on the installation.
Where should be the problem?

Try adding the "-v" flag (verbose mode) so you can see where it's hanging.
