D845Gebv2 Add-In Board And Peripheral Interface Connectors - Intel D845GEBV2 - OCTOBRE 2002 Manual

2.8.2.3 Add-in Board and Peripheral Interface Connectors
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.
