Really? So why all the hullabaloo about Triple Faults: http://www.rcollins.org/Productivity/TripleFault.html back in the day; and why did IBM set up the keyboard controller so it could send a RESET signal (so people could get out of protected mode)? Or is it that LOADALL (which was also undocumented early on, so maybe that's why the IBM thing) could be used to cause a triple fault? Noel
