This file is for alpha development kits ONLY. It should not run on your beta or retail kits, but even if it did, it wouldn't work. These files are backed up from my personal disks, and have been verified to work fine. The dumps are all 1:1, and of course include the boot sector needed to actually boot the files on the alpha development kits. Tons of early samples are included, and early tools like xbexplorer, which should help your fiddling, especially if you are looking to make your own alpha kit. You can find video of it in action here : http://ptoponline.com/?p=573 Download from MEGA Feel free to thank kl0wn as well!
