G'day All,
 
Well I have finally got the DS500/25 to netboot correctly from
a Solaris 2.4 server.
 
>From here on in it appears everything is documented in the
installation pages on www.netbsd.org.
 
Thanks to the following people for their help:
 
Simon Burge
David Conran
Michael L. Hitch
Tohru Nishimura
Jonathan Stone
 
Finally I can say "been there, done that".  Although it has
been a tough slog, I still believe it was easier than trying to
install NetBSD directly onto the drive from a SPARC.
 
I have documented all my stupid questions and will pass them
onto Simon Burge to be placed into an FAQ.
 
Regards,
Greg
