once you chose menu based install at the beginning, it's not possible to change your mind and get a shell (without switching virtual consoles, or rebooting).
shell based install works fine (when the console text is not garbled).
as for DHCP: the VPS provider itself doesn't run a DHCP server on their network. the network must be configured manually.
