Ive already done this with mine but with a switch and a sata socket on the back to switch between the xbox360 sata port and the port on the back. My idea is to have 2 switches one for the dual firware (1 with the xtr0800.bin and the other for the xtreme.bin) So when im finished I will be able to put both switches one way and plug sata into my computer to backup games and both the othere way to play the backups.
I was thinking of writing a Tut.
I will get some pictures as soon as I have the dual boot firmware installed as well..
