Hi, i've succesfully installed netbsd 3.0 on an ibook. This section:

http://ftp.netbsd.org/pub/NetBSD-daily/netbsd-3-0/200605220000Z/macppc/INSTALL.html#Examples%20of%20Open%20Firmware%20boot%20commands

shows some typical boot commands, but none of them appear to work. i can't 
boot from the hard drive. when i do devalias there is hd, ide0, ide1, 
ultra0, ultra1, scsi... all these are used in various ways in the 
examples, but i can't seem to use dir to get a listing and i don't know 
how to find out which of these i should use.

if it's any help, netbsd installed on something called wd0.

cheers

iain
