Party Setup Utility (default). Otherwise, place the jumper caps to pins 2–3 to
use the Intel ® Rapid Storage Technology.
5. Platform Enviromental Control Interface Setting (3-pin PECI1)*
When ASMB7-iKVM is installed, set to pins 2-3 for correct sensor information
of the Platform Environmental Control Interface (PECI). Set to pins 1-2 if
ASMB7-iKVM is not installed.
