as Jack mentionned earlier, you can do this using a debian installer cd.
- boot on the cdrom, enter install-power4 at the prompt
- follow the installer up to the point in mounts the cd
- press alt+f2 to access a shell
- use the following command to mount your root partition
# mkdir /rootpart
# mount -t ext3 /dev/sda4 /rootpart
provided the partition is the 4th one on the scsi disk and uses ext3.
you may need the device path to something like
/dev/scsi/bus0/target0/lun0/part4
- chroot in the partition, edit yaboot.conf and run yaboot
# chroot /rootpart
# vi /etc/yaboot.conf
# ybin -v
# exit
# eject
# reboot
i think only earlier versions of yaboot needed to have /proc mounted
from within the chroot. if so, use 'mount /proc' before calling ybin.
