When the system maintenance switch position 6 is set to the On position, the system is prepared to erase all
system configuration settings from both CMOS and NVRAM.

NMI functionality
An NMI crash dump creates a crash dump log before resetting a system which is not responding.
Crash dump log analysis is an essential part of diagnosing reliability problems, such as failures of operating
systems, device drivers, and applications. Many crashes freeze a system, and the only available action for
