Figure 15 shows the location of the add-in board connector and peripheral connectors for the 
Desktop Board D845GEBV2.  Note the following considerations for the PCI bus connectors (for 
both Desktop Boards): 
•  All of the PCI bus connectors are bus master capable. 
•  SMBus signals are routed to PCI bus connector 2.  This enables PCI bus add-in boards with 

SMBus support to access sensor data on the Desktop 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.
