2.8.2.4 Add-in Board and Peripheral Interface Connectors
Figure 15 and Figure 16 show the locations of the add-in board connectors and peripheral
connectors for the D850MD and D850MV boards respectively. 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, which 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
