You can access the redundant ROM by setting S1, S5, and S6 to On.
When the system maintenance S6 switch is set to the On position, the system will erase all system
configuration settings from both CMOS and NVRAM on the next reboot. Clearing CMOS, NVRAM, or
both delete configuration information. Be sure to configure the server properly to prevent data loss.

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 administrators is to restart the system. Resetting the system erases any information
which could support problem analysis, but the NMI feature preserves that information by performing a
memory dump before a system reset.
