Motherboard Overview

When replacing the motherboard, remove the service processor and System
Configuration PROM from the old motherboard and install these components on the
new motherboard. The service processor contains the Oracle ILOM system
configuration data and the System Configuration PROM contains the system host ID
and MAC address. Transferring these components will preserve the system-specific
information stored on these modules.
System firmware consists of two components: a service processor component and a
host component. The service processor component is located on the service processor
and the host component is located on the motherboard. In order for the system to
operate correctly, these two components must be compatible.
After replacing the motherboard, the host firmware on the motherboard might be
incompatible with the service processor firmware on the service processor that you
transferred to the new motherboard. In this case, the system firmware must be
loaded as described in
