Quick Startup Guide
If Novell's IPX protocol is being used, the link must be dialed first in
the Dial menu to obtain the server and route information needed by
the computer to boot up. Advanced users can use the Express L128T
S/T's Probe feature to periodically dial the access server to obtain the
route and server information, thereby removing the need to manually
dial the first time.
