Have you tried the basics first? Mapping is only needed if you want
to switch between multiple networking configurations, which i haven't
used. My interfaces is:

  auto lo eth0

  iface lo inet loopback

  iface eth0 inet static
    address 192.168.0.3
    netmask 255.255.255.0
    gateway 192.168.0.1

Do 'ifconfig' to show the status of your interfaces.
You should do '/etc/init.d/networking restart' to get
the new file read. IIRC, auto command does 'ifconfig' at
a lower level, and iface does 'route add'.

Other files to fill in manually are: /etc/hosts, /etc/host.conf,
/etc/hostname, /etc/networks, /etc/resolve.conf.
/etc/nsswitch.conf is used, but the default is usually ok.
