If you are running from the CD then you open a console window(clam shell icon on the taskbar) and run netcardconfig that will give you the opportunity to choose either DHCP or static settings if from the HD then in the console window use su then type in the root password and enter then you are root and can make any changes you want. When editing from the CD you can use sudo in front of a command to have root privileges while doing the editing eg. sudo gvim /etc/network/interfaces then you can save the file after the changes and not get the read only error.
