I recently got 5 xserve g5 cluster node systems and want to put ubuntu intrepid on them. I took a video card from another existing unit and used it along with the cdrom to do the actual installation which completed without a hitch. The problem I have is that as soon as I remove the video card and try to boot it the system just hangs and eventually the fans spin up to full speed. Is there a setting that can disable or otherwise stop the system from caring that there is no video and just boot it anyway?
