2.8.2.4 Add-in Board and Peripheral Interface Connectors
Figure 13 shows the location of the add-in board connector and peripheral connectors for the
D845HV board. Note the following considerations for the PCI bus connectors (for both boards):
• All of the PCI bus connectors are bus master capable.
• PCI bus connector 1 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
