Server component identification 17
Systems running Microsoft® Windows® experience a blue-screen trap when the
OS crashes. When this happens, Microsoft® recommends that system
administrators perform an NMI event by temporarily shorting the NMI header
with a jumper. The NMI event enables a hung system to become responsive
again.
