Intel Desktop Board D101GGC 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 transfer speeds up to 8 GBytes/sec. • PCI Express x1: one PCI Express x1 connector. The x1 interface supports simultaneous transfer speeds up to 500 MBytes/sec. • PCI Conventional (rev 2.3 compliant) bus: two 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 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. 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.

2.7.2.2
Add-in Card Connectors
The board has the following add-in card connectors:
•
PCI Express x16:
one connector supporting simultaneous transfer speeds up to 8 GBytes/sec.
•
PCI Express x1:
one PCI Express x1 connector.
The x1 interface supports simultaneous
transfer speeds up to 500 MBytes/sec.
•
PCI Conventional (rev 2.3 compliant) bus:
two 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 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.
