+If the system hangs on reboot after starting the service 'random,' shut down the board entirely, then bring it back up. This will completely reset the ethernet chip and prevent issues when bringing up the inet interface from a non-default configuration.  Typing 'Control-c' will interrupt the multi-user boot process and go to single user.  Type
