Brad>        /pci@80000000/@d/@2/@1:2

My mind is kind of out of control such that asking 
irrevalent things. Device name while booting is no use for 
Open Firmware boot. Sorry, Brad.

(2)
Then I was suspicious the part of ':2'.
What happens if just
boot-file /pci@80000000/@d/@2/@1:
set ?
I assume :2 is the partion number or SCSI id ?

OK. I now recoverd, what if
at Open Firmware,
   dev /
   dev /pci@80000000/@d/@2/
   ls
typed ? use the string you find there. If you got
sd@2:0, use
boot-file /pci@80000000/@d/@2/@sd2:
