Modificare il file /etc/rc.d/inet1, c'e' gia' qualcosa di predisposto
e non dovrebbe essere difficile. Allego il mio, non e' lungo, due
schede di rete, senza gateway, studiatelo. :)

Ciao.

Your ethernet card was not initialized properly.  Here are some reasons why this
may have happened, and the solutions:
1. Your kernel does not contain support for your card.  Including all the 
   network drivers in a Linux kernel can make it too large to even boot, and
   sometimes including extra drivers can cause system hangs.  To support your
   ethernet, either edit /etc/rc.d/rc.modules to load the support at boottime,
   or compile and install a kernel that contains support.
2. You don't have an ethernet card, in which case you should comment out this
   section of /etc/rc.d/rc.inet1.  (Unless you don't mind seeing this error...)
