Exploit
This is a very simple exploit. In earlier iBoots, if a parameter was given to the 'diags' command, then it would jump to whatever address argv[1] specified, but not before trashing the I/O table. You can run unsigned code using this, but there's no guarantee about the state of the processor.
In 2.0 iBoots, they check the permission register for this command, so the exploit doesn't work.
