NMI switch
The NMI switch allows administrators to perform a memory dump before performing a hard reset. Crash
dump analysis is an essential part of eliminating reliability problems, such as hangs or crashes in
operating systems, device drivers, and applications. Many crashes freeze a system, requiring you to do a
hard reset. Resetting the system erases any information that would support root cause analysis.
Systems running Microsoft® Windows® operating systems experience a blue screen trap when the
operating system crashes. When this happens, Microsoft® recommends that system administrators
perform an NMI event by pressing a dump switch. The NMI event enables a hung system to become
responsive again.
