296The first variable you'll find is called <c>config_eth0</c>. As you can probably
297imagine, this variable configured the eth0 network interface. If the interface
298needs to automatically obtain an IP through DHCP, you should set it like so:

300
301<pre caption="Automatically obtaining an IP for eth0">
302config_eth0=( "dhcp" )
303</pre>
304

306However, if you have to enter your own IP address, netmask and gateway, you need
307to set both <c>config_eth0</c> and <c>routes_eth0</c>:
308</p>
309
