2.8.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
•
One PCI Express x1 connector. The x1 interfaces support simultaneous transfer speeds up to
500 MBytes/sec
•
Two PCI Conventional rev 2.2 compliant local bus slots. The SMBus is routed to PCI
Conventional bus connector 2 only (ATX expansion slot 6)
. PCI Conventional bus add-in
cards with SMBus support can access sensor data and other information residing on the
Desktop Board.
Note the following considerations for the PCI Conventional bus connectors:
•
All of the PCI Conventional bus connectors are bus master capable.
•
SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI
Conventional bus add-in boards with SMBus support to access sensor data on the 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.
