2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express x16 3.0/2.x/1.x add-in card connector
• One PCI Express x16 3.0/2.x/1.x add-in card connector (x4 electrically)
• Two PCI Express x1 2.x/1.x add-in card connectors
• Three Conventional PCI bus add-in card connectors
• One PCI Express Full-/Half-Mini Card slot with support for mSATA
Note the following considerations for the Conventional PCI bus connectors:
• The Conventional PCI bus connectors are bus master capable.
• SMBus signals are routed to the Conventional PCI bus connectors. This enables
Conventional 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.
