To access the redundant ROM, set S1, S5, and S6 to on.
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.
CAUTION: Clearing CMOS and/or NVRAM deletes configuration information. Be sure to
properly configure the server or data loss could occur.
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 problems, such as hangs in operating
systems, device drivers, and applications. Many crashes freeze a system, and the only available action
for administrators is to cycle the system power. Resetting the system erases any information that could
support problem analysis, but the NMI feature preserves that information by performing a memory dump
before a hard reset.
To force the OS to invoke the NMI handler and generate a crash dump log, the administrator can use the
iLO Virtual NMI feature.
