2.8.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express x1 bus add-in card connector. The x1 interface supports simultaneous
transfer speeds up to 500 MBytes/sec.
• Two PCI Conventional (rev 2.2 compliant) bus add-in card connectors. 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
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 boards. 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.
