Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express x16 connector supporting simultaneous transfer speeds up to 8 GBytes/sec.
• One PCI Express x1 connector. The x1 interfaces support simultaneous transfer speeds up to
• One PCI Express x16 connector supporting simultaneous transfer speeds up to 8 GBytes/sec.
• 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.
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
• 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 boards. The
specific SMBus signals are as follows:
specific SMBus signals are as follows:
The SMBus clock line is connected to pin A40.
The SMBus data line is connected to pin A41.
NOTE
The PCI Express x16 connector is configured to support only a PCI Express x1 link when the
Intel GMA900 graphics controller is enabled.
