imac rev D 7.0 rel booting issue

[Richard DeLaurell]

I have just joined this list and don't know if this is an appropriate place
to ask, nor am I aware of any archive to search to see if my question has
been "asked-and-answered" already.

I have installed 7.0 Release for ppc on an iMac 333 rev D.

My first five partitions are the required mac hd drivers; the sixth is mac
os9.  It is also where I keep the boot loader file and kernel for the NetBSD
2.0.2, that which resides on partitions 7-10.

Mac os9 takes up about 3g, and NB2 maybe 10g on my hd.

I installed FreeBSD 7 on partitions 11-16; those begin at 11g.  I copied the
"boot" file from the install cd to the top directory of the os9 (as I did
for NB2), however, when I try to boot FB7 at the openfirmware (3.0.d) prompt
thus:

0>boot hd:,\loader hd:11

the loader does its duty and then stalls.

If I change the boot command to:

0>boot hd:,\loader

it reports that it "cannot load 'kernel'."

I have tried copying a "generic.aa" file from the install cd's "kernels"
folder to sit beside the loader file on the os9 partition, but to no avail.

(Sorry for the lengthy details, but here's the question) I seem to remember
something about the imacs having an 8g limit.  Is this what I am running
into?

Why does it not affect the NB2 installation?

Again, if there is an archive I could search for previous answers to this, I
would be glad to know of that, and I apologize if this is a repeat.

Thanks for any help.
