A SunOS filesystem is compatible with NetBSD.  You can format, partition,
mount, and untar NetBSD onto the other drive under SunOS.  The tricky part
will be trying to boot from that drive without the aid of NetBSD to
install the boot blocks.

Try installing a SunOS boot block on the drive.  However, instead of using
the secondary SunOS 'boot' program, use the NetBSD ufsboot file.
(Found in /usr/mdec on NetBSD.  See the SunOS installboot man page and
this will all make sense.)

Once you have NetBSD running, you will want to go into single user mode
and run fsck -2.  This will update the filesystems to the more modern
NetBSD format..
