I'm just wondering if there is a way to install a fiber optic port on the motherboard of an xbox360 (older version, the one without a direct connection to fiber optic cable). I recently purchased a fiber optic adapter. i plugged a fiber optic cable to it to my surround system but with no luck. I don't know what the problem is, I doubt that there is a problem with the motherboard or the adapter port. could someone please shed some light on this matter?
