Figure 11 shows the location of the add-in board connector and peripheral connectors. Note the following considerations for the PCI bus connectors:
•All of the PCI bus connectors are bus master capable.
•SMBus signals are routed to PCI bus connector 2. This enables PCI 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.
