On the "Network Configuration" screen you are presented with a menu:
Method to obtain network configuration? [dhcp] 1. dhcp 2. static >
At the "" prompt choose one of the three, the third option assumes you know what you need to do at the shell prompt to get your network configured.
Depending on which option is chosen, the next screen that appears will either be the "DHCP Configuration" screen, or the "Static IP Configuration" screens.
