Add-in Board and Peripheral Interface Connectors

Figure 4 shows the location of the add-in board connector and peripheral connectors for the
Desktop Board D845GLLY. 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.

Not all PCI video cards can be used in PCI bus connectors 1 and 2 (the PCI bus connectors closest
