Help with install on powerbook g3

Hello,

I am trying to install NetBSD onto a Powerbook g3.

I want the OS to boot from the laptop's hard disk.

Here is the powerbook's information:
powerbook g3, 250mhz
open firmware 2.0.1
family number: M4753

I have already installed NetBSD into the machine by
netbooting
it.

However I can not seem to get it to boot from the disk now.

Is there some magic proceedure/tool I can use to tell open
firmware to boot this thing?


thanks,
