I've been trying to get a clear answer to this on the Xbox forum but its not happening. I have my Xbox connected directly to my NIC card using a patch cable to connect to Live. A question was brought up on which type of cable is needed for System Link (connecting two Xbox's together). The most common answer (which I understand) is a cross-over cable since your connecting two NIC cards together. But what I dont understand is why can I use a Patch cable to connect my xbox directly to my PC and I cant use a Patch cable to connect an Xbox to an Xbox?
