eth1 and eth0 fail at startup

[Sigfrid]

I'm running an tangerine ibook with os 9 on one partition and ydl 3 on the
other.  When I start up under ydl the system fails to find ip address's for
eth1 and eth0, and when I try to start up the 'network' system setting it
crashes.  I know that at least my ethernet port is ok because it works under
9.  I'm a newbie and haven't found much in my search on the internet about
this.  Help me get linux working on the net.
