Add-in Board and Peripheral Interface Connectors

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.
•
PCI bus connector 2 has SMBus signals routed to it. This enables PCI bus add-in boards with
SMBus support to access sensor data on the 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
