Intel Desktop Board D510MO Technical Product Specification 2.2.2.2 Add-in Card Connectors The board has the following add-in card connectors: • PCI Express x1 Mini Card (rev 1.2 compliant) connector • PCI Conventional (rev 2.3 compliant) bus connector Note the following considerations for the PCI Conventional bus connector: • The PCI Conventional bus connector is bus master capable. • SMBus signals are routed to the PCI Conventional bus connector. 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. ⎯ The SMBus data line is connected to pin A41. The PCI Conventional bus connector also supports single-slot and dual-slot riser cards for use of up to two bus master PCI expansion cards. In order to support two PCI bus master expansion cards, the riser card must support the following PCI signal routing: • Pin A11: additional 33 MHz PCI clock • Pin B10: additional PCI Request signal (i.e., PREQ#2) • Pin B14: additional PCI Grant signal (i.e., GNT#2) 2.2.2.3 Power Supply Connector The board has a 2 x 12 power connector (see Table 27). This board requires a TFX12V or SFX12V power supply. Table 27.

2.2.2.2
Add-in Card Connectors
The board has the following add-in card connectors:
•
PCI Express x1 Mini Card (rev 1.2 compliant) connector
•
PCI Conventional (rev 2.3 compliant) bus connector
Note the following considerations for the PCI Conventional bus connector:
•
The PCI Conventional bus connector is bus master capable.
•
SMBus signals are routed to the PCI Conventional bus connector.
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.
⎯
The SMBus data line is connected to pin A41.
The PCI Conventional bus connector also supports single-slot and dual-slot riser cards
for use of up to two bus master PCI expansion cards.
In order to support two PCI bus
master expansion cards, the riser card must support the following PCI signal routing:
•
Pin A11: additional 33 MHz PCI clock
•
Pin B10: additional PCI Request signal (i.e., PREQ#2)
•
Pin B14: additional PCI Grant signal (i.e., GNT#2)
2.2.2.3
Power Supply Connector
The board has a 2 x 12 power connector (see Table 27).
This board requires a TFX12V
or SFX12V power supply.
