I got it from GA Tech's mirror
http://mirrors.fedoraproject.org/publiclist/Fedora/7/ the ppc version. I tried both the Core 7 and 5, did the sha1sum to make sure it was correct
I have used many different bootloaders not sure if that was the problem.
The final attempt I used a bittorent from the site above.
I also used
www.louiscandell.com instructions I really haven't gotten to the install part.
I used Vista to put the iso images on the disk, a few times it wasn't burning correctly but the last few times i checked the directory and it seemed correct
