Well, this is interesting. Some out-of-the-box thinkers at DFI decided that it was silly to limit ourselves to one computer per box — so they made a motherboard that will support two completely different configurations that you can switch between at will.
You could do a high-power and low-power thing, as they demonstrate with an Atom and traditional socket 775-based setup living together on the board, or you could have similar setups running different OSes. The possibilities are… well, they’re not endless, but they’re certainly more than you had before.
