•
SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI
Conventional bus add-in boards with SMBus support to access sensor data on the Desktop
Board. The specific SMBus signals are as follows:
 The SMBus clock line is connected to pin A40.
 The SMBus data line is connected to pin A41.
