It looks like it is connected to a compact flash reader. Is that what it is? It isn't listed in the description. If not, what is it?

It is actually a smart media card readers, and that is an option for the barebones. I didn't order them with that option. It added significantly to the per unit cost, and I don't know it is bootable. If I get the one I have here to boot that way I will order some with this option.
