I dug out my old dreambox 500 as i was going to set it up in the spare room so i installed Commando 14.6 so far its great but i haven't played about with a dm for a long time and am new to this image. Theproblem is i cant get my head around how to install a cline and a nline on image

Sorry sorted it i didn't even see the extras menu looking right at me
