Hi, I have a couple Z800's lying around my office, unfortunately one of them is missing a graphics card. I borrowed one from another machine and put it in to build it, then returned the card to the machine once I was done. Now when I try to boot it up it gives the 6 beeps/red light combination which indicates that the graphics card is missing. Is there some way to tell it to shut up and just boot? I really don't want to have to spend money on a graphics card for this box considering it will be running Linux in headless mode.
