2.8.2.3 Add-in Board and Peripheral Interface Connectors
Figure 14 shows the location of the add-in board and peripheral connectors for the Desktop Board
D845PEBT2. Note the following considerations for the PCI bus connectors:
• All of the PCI bus connectors are bus master capable.
• The SMBus is routed to PCI bus connector 1 or 2 depending on the board’s AA number labeled
on the board’s front right corner (see section 2.8.2.1 on page 57). This enables PCI bus add-in
boards with SMBus support to access sensor data on the Desktop Board D845PEBT2. 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
