Have you tried to set bootflags:


ncpi=0x2000 OR npci=0x3000


I read this on the installation guide from Hackintosh Zone.


It says something like: 


If installation hangs at PCI Configuration Begin, try: npci=0x2000 OR npci=0x3000


If it hangs at DSMOS has arrived, try bootflag -s then type grafix on superuser console and press enter.


username and pass if you can´t create account on first boot: root | niresh
