You can't boot without mounting any filesystems at all; / must be
mounted, at a minimum.

What kind of disk is it that can sit on either SCSI or IDE?  Or do you
have some kind of adapter in front of it in one case?  Could the
adapter be related?

One doesn't.  You need to get / from _somewhere_.  Perhaps for your
purposes it might be a good idea to boot with / on NFS?  I don't recall
enough of mac68k to say how, but most ports have _some_ way to specify
"prompt me for root &c" when booting.

Not me.
