These are the specs, if you need more info let me know. Ive tried efi and efi legacy, iboot 3.0.2 and iboot legacy. I have burned kext beast and multibeast on cd's as well. Im trying to install snow leopard 10.6.1-10.6.2 AMD Intel... And I cannot seem to get it working, I keep getting errors during the start process after the iboot "f5" area. Any help would be appreciated
