Re: I'm such a newb... i need help... PPC install help
Welcome to LQ!
I think I know what your problem is. If you downloaded your image with your mac, make sure OSX doesn't create a disk volume. If you copy the automatically created volume to CD, it won't boot. Instead you should burn the image (*.iso file) with your CD burning software.
Also, make sure you downloaded the correct images (you need the PPC, not i386 ones).
