Basically it boots to a yellow screen. I did a lot of heavy reading on the disc after buying it and I guess it is able to load automated test programs connected to an external machine. Something about connecting a device to the 4th USB port on the xbox.
For me it does nothing, and it does not boot in a 360 if you are wondering.
But if you are into rare xbox stuff I think this is about the rarest it gets. I do not think anymore of these exist in the wild.
Try not to PM if you can, it's a pain to clear out my inbox.
Also if any of you are hardcore with Dev machines let me know I would like to know if this disc has any potential being a bootloader and all. I would definitely consider shipping this out for free if you honestly believe you are the best person to have this disc.
