help installing lawlessPPC 10.5.4 on phenom AMD

[pepspeps]

I'm pretty lost on how to install this so i really need some help.
i seem to get stuck at "waiting for root device" i never get into the install.
i have tried -v -f -x -s but i remain stuck at the same part.

I have a

AMD Phenom 64 8450 X3 2.10GB
3GB DDR RAM
SATA 500GB
GEFORCE 9600GSO 768MB
DVD-RW (bio not telling me if it's master or slave it is the only disk drive i have)

i have vista currently installed but i want to install leopard on another partition which i named leopard (right now is a logical drive, i'm not sure how to switch to primary)

anyway i'm not sure what i'm actually suppose to do, i was really hoping that popping the cd would of been enough =P

thank you for the help.
