NMI header
The NMI header enables administrators to perform a memory dump before performing a hard reset. Crash
dump analysis is an essential part of eliminating reliability issues, such as hangs or crashes in operating
systems, device drivers, and applications. Many crashes can freeze a system, requiring you to perform a
hard reset. Resetting the system erases any information that supports root cause analysis.
When a Windows® operating system crashes, a blue-screen trap appears. When this trap appears,
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.
