Karl provided the answer.
1. Set CD to target 3
2. boot boot /sbus/esp@0,800000/sd@0,0 -sr
3. edit /etc/vfstab to reference target 3
4. change disk jumpers to target 3
5. power on and everything works as target 3
Another suggestion was to setenv boot-device
however, the values that I could see are 'disk' or 'net'
It was alread set to disk.
I did not see how to associate the prom device aliase, disk,
with target 0.
Thanks
