NMI functionality

An NMI crash dump enables administrators to create crash dump files when a system is hung and not
responding to traditional debug mechanisms.
Crash dump log analysis is an essential part of diagnosing reliability issues, such as hangs in operating
systems, device drivers, and applications. When crashes freeze a system, administrators must cycle the
system power. Resetting the system erases any information that support issue analysis, but the NMI feature
preserves that information by performing a memory dump before a hard reset.
The administrator must use the iLO Virtual NMI feature to force the OS to invoke the NMI handler and
generate a crash dump log.
