On the "Addressing Method" screen you will see a menu like this:
Method to obtain network configuration?
=> 1. dhcp
2. static
3. Exit with no configuration
[1] >
Choose "dhcp" (1) if you are on a network with a DHCP server (could be a server computer or a small firewall/router device), or choose "static" (2) if you know your IP address information (address, netmask, network, gateway, and dns server). Only choose "Exit with no configuration" (3) if you only want to install software package from the Cinch cdrom.
