i have already installed NetBSD on the hard drive, now when i try to boot 
without open firmware, i just get a flashing question mark icon.

reading this section of the install guide (which i apparently completely 
disregarded the first time through :-S !!):

http://ftp.netbsd.org/pub/NetBSD-daily/netbsd-3-0/200605220000Z/macppc/INSTALL.html#Partitioning%20your%20hard%20drive%20for%20NetBSD

i see that i am able to create these partitions using pdisk. i presume i'm 
able to do this by booting into the shell from the cd.

i gave it a go, but was a big confused. i deleted existing partitions and 
tried to make a new one at base 4, 200 blocks long (200 blocks being 
100x1024/512 for the HFS partition) but it told me that the partition was 
not big enough, however it is some 30,000 blocks long.

can anyone tell me the set of commands to use to create these partitions 
and copy ofwboot.xcf in there from the cd?

cheers
