Sorry, I was looking at the link for the card and found this, in BRIGHT RED
Important Note: This board is NOT a video card. It has no display outputs for connecting a monitor. It is a processor that offloads the computation from the computer's CPU. Also note that for operation under Windows XP, this board requires a NVIDIA graphics display board or motherboard NVIDIA graphics. This is not a requirement for Linux operation.
I think it would be hard to make a dummy plug for this, since you need a GFX card for display, and this one has no outs.
