First, you need to get a vmlinux.coff file from ftp.linuxppc.org/kernels/
or off of your CD in the /kernel directory. Just copy it onto a Mac
formated 1.4 meg floppy disk.

Then set the boot variables program to 
>boot-device     fd:vmlinux.coff
>boot-file        root=/dev/sda7 ( or whatever partition you want )

and then reboot.
