I am having trouble booting into the SL 10.6 install disk using the Nvidia version of iBoot, as the error "firewire unable to determine security-mode" is halting the boot process... My PC's specifications are as follows: Intel Core i7 920, Nvidia GTX 470, 4gb DDR3 RAM, ASUS P6T v2 Deluxe Motherboard.
Thanks! (Note: I have already tried safe mode)
