Can't boot from a PPC mac
I have just completed the installation process Debian "potato" onto a PPC
Mac 7600/120. I followed the instructions through to "Make Linux Bootable
directly from Hard Disk" and then "Executed a shell" and attempted to run:
nvsetenv ofpath /dev/sda6
I get the message "no variable ofpath"
When I reboot it goes directly into the Mac O/S and I can't get into Linux.
Can anyone recommend an alternative to boot directly into Linux please?
