I have a brand new iMac (well, a month old--dalmation, 500mhz,
slot-load cdrw).

I have the drive (20G) partitioned thus:
 3G MacOS/hfs+
 16G au/x root
 500m au/x swap

I'm booting of a cd I made with the netbsd.ram.gz kernel and ofwboot.elf.

I get to the stage of the install where I confirm that I want to install
to hard disk, right at the very beginning of the process, and it tells me
it can't find any hard disks for use with netbsd.  :-\

I looked briefly for answers on the lists and on the site, but being new
to all this BSD stuff (a recent convert from OS X) I thought I'd ask.

Many thanks,
Jeff
