How to get back to Sun's setup screen...

[George W. Fleming]

When you start up a Sun for the very first time, and when you've just
installed OS4.1.1, you get a menu screen asking you to enter some network
informations (hostname, IP address, NIS, etc.).  Does anyone know how to
reset the Sun to this initial state?  

It would be nice to simply bring up this screen again instead of changing
the information manually in /etc.
