hey people. first of all mad props to zephyroth. This disk is the closest ive got to install on my amd machine. After a lot of adjustments (dvd and hdd on same ide ribbon) ive managed to get the installer to run throught to I minute left hang (Ive used the wikidiot reinstall guide and it had no effect, still died at the same point), then the screen turns grey, the apple loading circle shows and the machine powers off. The installer log shows dummy bless (or there abouts). On reboot in verbose mode I get the 'still waiting for root device' message. It doesnt matter if I try MBR or GUID, install with or without kexts, the install alwats ends up the same, I have also burned several disks using alcohol in windows and toast on a kalyway intel machine.
After lurking here and insaelymac for a few days the ive seen a few people with same problem and similar processors and the only theory ive come up wiht is that its a problem with the athlon x64 socket 754 family. Other than that i have no theories. If anyone has any ideas feel free. Heres the specs;-

mobo-asus k8s-mx
chipset- sis 760gx
ram 2x512 pc3200
sound- using an external sb live (no kext required just plug and play after install)
graphics -nvidia geforce 6600 128mb agp.
hdd-ide 40gb

Should probably mention I did have an extremely unstable tiger 10.4.6 install on this machine.
Again thanks a lot zephyroth.
Thanks.
