In the event that the processor is tri-stated using power-on-configuration controls, the
PECI client will also be tri-stated. Processor tri-state controls are described in

Device Discovery
The PECI client is available on all processors. The presence of a PECI enabled processor
in a CPU socket can be confirmed by using the Ping() command described in
in a CPU socket can be confirmed by using the Ping() command described in
. Positive identification of the PECI revision number can be achieved by
issuing the GetDIB() command. The revision number acts as a reference to the PECI
specification document applicable to the processor client definition. Please refer to
specification document applicable to the processor client definition. Please refer to
for details on GetDIB response formatting.

Client Addressing
The PECI client assumes a default address of 0x30. The PECI client address for the
processor is configured through the settings of the SOCKET_ID[1:0] signals. Each
processor socket in the system requires that the two SOCKET_ID signals be configured
to a different PECI addresses. Strapping the SOCKET_ID[1:0] pins results in the client
