NMI jumper

The NMI jumper 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 OSs, device
drivers, and applications. Many crashes can 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® 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.
