bootxx 1.13 loads ofwboot to 0xe00000.

The problem is that there is dark magic in how the bootable CD rom get=20
made, and we didn't update it when we changed ofwboot.

Luke and I just spent a fair bit of time talking about this, and we really=
=20
don't understand how the current code can hope to work. Thus I find it=20
unlikely that we will be able to cook up something using the new bootxx=20
any time soon.

As an interum step, could someone who can make NetBSD iso images using the=
=20
distrib/cdrom stuff try the attached patch? It changes what I think is the=
=20
load address for ofwboot.

Take care,

Bill
