Actually after thinking about it, it doesn't matter how much of the harddrive the BIOS can "see". Using this exploit will not allow you to easily install a bigger hard drive, so mod chips are still necessary in the end. So what is the big deal with this exploit, there is none, people are making it more than it is, the only thing that would be bad, is being able to play backups on Live, which is easily stopped by MS, and isn't a big deal anyway, cause if you modify the code of your game for cheating, I know that in system link games, you can't connect with other Xboxes, so it is surely the same on Live. Alll you can do is play a backup off the hard drive, big whoopdie fricking doo, people are already doing it with mod chips. And like I said before, the most a noob could fit on the standard hard drive is one, maybe two games max. This will NOT kill the Xbox anymore than mod chips could kill it and obviously haven't.
