Hi Bryan,

We've all been truogh these initial booting problems. Once you figure it out, it's not so bad, though. I hope the following helps:

You (most likely) need to enter:
  boot scsi/sd@3:0,\OFWBOOT.XCF
or
  boot scsi/sd@3:0,\ofwboot.xcf

If you want to, you can append the kernel name (netbsd.macppc) as follows:
  boot scsi/sd@3:0,\OFWBOOT.XCF NETBSD.MACPPC
or
  boot scsi/sd@3:0,\ofwboot.xcf netbsd.macppc

No, this is something different. The
  ls
command in open firmware shows you the content of the open firmware device tree, _not_ the content of the device itself. So you just see what open firmware knows about the scsi device. It shows you that it has sd and st which are disc and tape drivers.

To see what devices are present on the scsi bus, you need to enter
  dev scsi show-children
(but often this doesn't work -- for some strange reason).


Good luck,
Daniel
