Intel Desktop Board D955XCS Technical Product Specification 2.7.2.2 Add-in Card Connectors The board has the following add-in card connectors: • PCI Express x16; one connector supporting simultaneous transfers up to 8 GBytes/sec • Secondary PCI Express x16/x4 bus; one connector supporting simultaneous transfers up to 2 GBytes/sec • PCI Express x1; one connector supporting simultaneous transfers up to 500 MBytes/sec • PCI Conventional (rev 2.3 compliant) bus; four PCI Conventional 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 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 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. 2.7.2.3 Auxiliary Front Panel Power/Sleep LED Connector Pins 1 and 3 of this connector duplicate the signals on pins 2 and 4 of the front panel connector.
