Or is this just not never modify the bootstrap partition, edit the magicboot= line in /etc/yaboot.conf to point to an alternate script. you can make a copy of the /usr/lib/yaboot/ofboot file, then find and change the line: " screen" output to " ttya" output later im going to fix this so it won't have this problem. -- Ethan Benson http://www.alaska.net/~erbenson/ ** Sent via the linuxppc-dev mail list.
