1. Intel will start shipping Xeon processors by September 24th that take advantage of this and plan to add support for NX in all of its P4 CPUs in Q4.
  2. There is now a software DEP built into SP2 which you can activate!  It probably isn't as robust as the hardware DEP listed above, but it’s there.  If you go My Computer – Properties – Advanced tab – Performance Settings button – Data Execution Tab you can turn on the software.  Pretty cool, hey?
