2.8.2.3 Add-in Board and Peripheral Interface Connectors
Figure 6 shows the location of the add-in board connector and peripheral connectors for the
Desktop Board D845EPI. 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, enabling PCI bus add-in boards with SMBus
support to access sensor data on the Desktop Board. The SMBus signals are as follows:
 The SMBus clock line is connected to pin A40.
 The SMBus data line is connected to pin A41.
