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.
IMPORTANT: Before using the S7 switch to change to Legacy BIOS Boot Mode, be sure the HP
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 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.
To force the system to invoke the NMI handler and generate a crash dump log, do one of the following:
•
Use the iLO Virtual NMI feature.
•
Short the NMI header (" System board components " on page 12 ).
For more information, see the HP website ( http://www.hp.com/support/NMI ).
