Xbox 360 Backup Discs Bootable

An anonymous reader writes "The firmware of the Xbox 360 DVD drive has been hacked, allowing users to boot backups of games on the new Microsoft console. A group of hackers on the xboxhacker.net forum managed to trick the DVD firmware into reporting a recordable disc as an original Xbox 360 disc. This means that it will not allow booting of unsigned homebrew code (like Linux), as the signature check is not bypassed. This hack will just trick the Xbox 360 into thinking you inserted an original Xbox 360 disc, so it'll only boot unedited executables. A video has been released, the hack has not been released to the public (because it will be mainly used for piracy), but all the research of the last few months is publicly viewable."

Ability to boot non-Microsoft code more useful

[Animats]

This is the "piracy" hack. A way to cleanly boot non-Microsoft content would be more useful. Microsoft probably couldn't do much about that legally; if you own the unit, you have no obligation to play only approved content.

Surprised it took this long

Frankly I'm surprised it took this long, given that the Xbox 360 will boot burned CDs/DVDs for backwards compatibility updates.

I always thought that was a pretty good area of attack right there.

Well, it doesn't help that much, as it's the signature that determines how a valid image may be started (and no commercial game will say "burned booting OK"). Now, all software written by MS really "sees" the disc as a real DVD, completely independent of whether booting from burned DVDs is supported or not. The only way to block this would be to block flashing DVD firmware (wise) or blocking reading burned discs in hardware. The latter would of course make it less usable for playing CDs or video in more or less legitimate ways that MS still wants to support.
