Well... I booted the installation kernel and used Sysinst to
reformat 
my Mkfs created partitions.  Upon reboot, my machine failed
to boot 
into Macintosh.  It must have messed up the MacOS partition.
 I had to 
use Macintosh Disk Tools to format the drive and reinstall
MacOS and 
everything else leaving all but the MacOS partition free. 
Then, I used 
Sysinst to create a root/usr and swap partition.  Upon
reboot, my 
machine, once again, failed to boot into Macintosh and it
looks like 
I'm about to reformat the drive and start all over again. 
What's up 
here?  Has anyone actually used Sysinst to set up partitions
and then 
install NetBSD from the MacOS installer?  It doesn't seem to
work for 
me.

Cheers, Tom
