I have the same problem, I'll share my scenario
My specs are: i7-4770k, z87mx-d3h, msi gtx 780.
I created USB installer by [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], OS X 10.8.5.
In bios, I resets settings to optimized settings, then disabled the inboard graphics, selected PCI 1 as initial display.
Everything went smooth, from creating the USB until the first boot. When I first booted into the OS X hard disk, it boots fine, I installed the drivers with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], I restarted the PC, then I got stuck at booting into the OS X.
The v flags shows me the lines then it stops/stuck at this
( PCI Configuration Begin )
I'm guessing you had the message in the same place? After booting from the hard drive?
LooL, I. Not allowed to write utility's name from outside of insainalymacs!
I used the ones from tonymacx64
