The Hidden Boot Code of the Xbox

Device666 writes "In order to lock out both copied games as well as homebrew software, including the GNU/Linux operating system, Microsoft built a chain of trust on the Xbox reaching from the hardware to the execution of game code, in order to avoid the infiltration of code that has not been authorized by Microsoft. The link between hardware and software in this chain of trust is the hidden "MCPX" boot ROM. The principles, the implementations and the security vulnerabilities of this 512 bytes ROM will be discussed in this wikipedia article entitled How to fit three bugs in 512 bytes of security code."

    So it seems someone doesn't know the difference between a page with wiki technology and Wikipedia.

    The thing everyone needs to remember is that slashdot is akin to Norman Bates, a lot of them are confused, a lot of them crossdress and are very often psychotic.

    So, the next time you see a dupe.. remember, be quiet.. or you could be murdered by a crossdressing psychopath.

    Is that over or under Microsoft's par?

      Neither, really. 3840 bugs should be enough for everyone.

    Easy. Just put one bug in every 170.666666666666667 bytes and you will be done.

    At least Microsoft provides the same level of security to it own hardware as its does yours. You can't accuse Microsoft of playing favorites.

    I suspect that they spend most of their time finding all the non-duplicate, insightful articles that have been submitted so that they can reject them.
