I'm no expert, thats for sure. But i've been told it can't be done. UNLESS you make that crossover cable a straight cable. http://www.littlewhitedog.com/content-8.html I think this is probably a good place to learn how to do that. This is what i've done to mine, and it works great, FTPing and playing on XBC. Good luck! P.s. You might want to practice on a "not used" ethernet cable before you actually do the one you plan on using. Just a suggestion.
Yes you can use a crossover cable to connect to your xbox. Once you connect to your PC bridge your internet connection with your Local Area Connection
okay , I dont want to screw up my ethernet cords so... I dont think I will be doing that (I dont think) and , when I try to bridge the connections , it just says that both of my connections are unplugged.
