OK - NetworkManager is NOT running. Good - makes things easier.

Good - looks like eth0 might already be ready and running. Does it show
up in "ifconfig"? If it does, can you send us the line that looks like
this (some words may be missing):

           UP BROADCAST MULTICAST  MTU:1500  Metric:1

What does "got it" mean? That you saw ping responses? Please tell us
what the responses were (one is enough if they were all very similar).

If you did get ping responses that is good news, it means that the
interface is basically working.

This suggests that you left those incorrect "broadcast" and "network"
entries in /etc/network/interfaces. If so, make sure
that /etc/network/interfaces contains only the lines I supplied, and try
again.
