that would work too..

no, you don't specify a file to the boot-device variable, OF does not
know how to read filesystems.  it will simply load a bootblock off the
bootable partition (if you specify partition 0) the bootblock is
quik's first stage loader which loads the second stage loader from
your root filesystem, that in turn knows how to read ext2, it reads
the /etc/quik.conf and loads your kernel.  

you need scsi/sd@3:0 or scsi/sd@3:3, either should work.

yes, Cmd+Opt+p+r from a cold boot will reset it.  the problem is there
is no OF video driver in the 7200 so OF sends everything right out the
serial port.   it could be the path is wrong, or you forgot to run
quik, or your quik.conf is wrong.  if you have a second machine around
or a dumb terminal you can access the OF console and see exactly what
went wrong.  

check your /etc/quik.conf (after chroot /target) it should be
something like this:


image=/boot/vmlinux-2.2.18pre21 ## or whatever, don't use a symlink

then run /sbin/quik, set the boot-device variable, light candles,
chant and reboot.
