The local college where I work has acquired a number of Sun4c's, donated 
by a federal agency.  As is customary with such donations, the disks have 
all been wiped clean.  I would like to make use of these machines, and 
netbsd seems a good way to do this.

What I would like to do is create a bootable netbsd root file system on 
one of the external SCSI disks from another machine, viz., a PC running
netbsd.  Can I do this?  Can I install a sparc bootblock from a non-sparc 
machine using nothing more than disklabel?
