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 11). 
For more information, see the HP website (http://www.hp.com/support/NMI). 
 
DIMM slot locations 
DIMM slots are numbered sequentially (1 through 8) for the processor. The supported AMP modes use the 
letter assignments for population guidelines.
