What I thought I'd said was that we should work out the details on
"standard" machine configurations first, then deal with the special cases
of machines that have been upgraded with different disks, interfaces and
such. Since Apple has released standard systems with various versions of
OF that don't all work the same, I think this is an excellent approach.
My original statements about special case machines was based on my onw
experience and belief that changing the machine configuration _may_
introduce additional problems or mask what is really happening in OF. I
certainly beleive that I've seen this first-hand with my B&W G3; adding
an IDE disk to the secondary controller created a situation where the
CDROM became unbootable, even for MacOS. Removing the disk cleared up
the problem. I have a feeling that if this is happening on other's
machines as well it make be confusing the main issue of learning how to
use OF to boot NetBSD from disk or CD.

I had the same experience with System Disk that Henry describes. After
that I'm kind of leary about using it again since I have no idea what it
will modify. I'd feel much more comfortable dealing with a set of
instructions that tell me how to get into OF and set variables by hand
and why I'm doing it. That way I can keep a record of what they were
before I changed them and have some hope of getting my system back if
things don't work out.

I finally got my MacOS X CD in and I have a utility that can format and
dump the Disk Partition tables. Maybe this will give someone a clue
about how to build a CD that is bootable on different systems so we can
make the appropiate changes to mkhybrid. Is anyone interested in a copy
of the dump?
