The Hidden Boot Code of the Xbox

Posted by CmdrTaco on from the stuff-to-read dept.

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."

    In all fairness, the previous posting of this had NOTHING about Wikipedia in it. Perhaps that was the intended news to spread?

    That's not a wikipedia article, that's an article from a wiki running mediawiki.
