When system maintenance switch S6 is set to the On position, the system is prepared to erase all system
configuration settings from both CMOS and NVRAM.
IMPORTANT: Before using the S7 switch to change to Legacy BIOS Boot Mode, be sure the
HPE Dynamic Smart Array B140i Controller is disabled. Do not use the B140i controller when
the server is in Legacy BIOS Boot Mode.
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.
