I don't think that making code for accessing the disk or even one Mac
partition with a BSD disklabel is that hard.  Probably a couple of days,
but I'm personally sort of lacking the time and motivation to bother.

You get the whole scsi disk.

This will make identical Mac/MacBSD disks.

Presumably, someone motivated to solve the problem (e.g. you) will
figure out how to derive or guess the large number of things that we
currently obtain from MacOS because there's nowhere else to get the
information and no documentation.

In order to remove our reliance on MacOS, we would probably have
to enter a non-disclosure agreement with Apple and pay them $$
to get information on the boot process.  Then there would be a
proprietary chunk of MacBSD, copyrighted by Apple and probably
not freely distributable.

Feel free to try what we haven't been able to do for three years.
Don't even bother saying that we "must not be any good, then,"
because lots of people have said that before and then failed to
prove their point.

Sure.  Let us know when the floppy driver works.

This whole conversation is really getting stale.  All of the
contributions to MacBSD came from people who, instead of saying
"Let's do it this way," said, "it's done; where should I put it?"
