re core only or not. This is what I did on my core, many,many moons ago: I installed a hybrid with 800x600 resolution, UI1 and analog stereo. Should work on most any gfx chip set. Did all the usual setup wizardry on the core. Changed AutostartMedia in /etc/pluto.conf to 0, rebooted, and presto: Core only. The core is now in the attic, rarely to be looked at.
