I wonder if anyone could help with a booting problem?

I've got a powerbook g3 (I believe it's a wallstreet, but without the 
ID marks, I can't be entirely certain) running open firmware 2.0.2.
I have no cd drive, but I've managed to run the installer via a 
net-install. All seemed well, but I'm damned if I can get it to boot 
from the hard drive!
My problem is stemming from the fact that I can't work out what the 
boot command should be, so if anyone has a cheat sheet, I'd be most 
grateful. I've tried everything I can find on thar intraweb, but to no 
avail. (if it's any help, there's no 'ide' alias, just ata0 (or 
ata-int) through 4, and scsi & scsi-int)

TIA,
Rich
