2.6 IMB-Q354 PCIe Bus Components
2.6.1 PCIe Bus Overview
The IMB-Q354 has one PCIe x16 channel from the Intel® Q35 Northbridge and six PCIe
x1 lanes from the Intel® ICH9DO Southbridge. The PCIe bus lanes are interfaced to the
following devices.
One PCIe x16 lane is connected to one PCIe x16 graphics card
Four PCIe x1 lanes are connected to one PCIe x4 expansion card
One PCIe x1 lane are connected to one Intel® PCIe GbE device
One PCIe x1 is shared with the Intel® ICH9DO Gigabit LAN Connect
Interface (GLCI), which is connected to a Intel® 82566DM Gigabit platform
LAN connect device
2.6.2 PCIe x16 Slot
The Intel® Q35 Northbridge chipset has one PCIe x16 port reserved for a PCIe x16
graphics card. The PCIe x16 lane is interfaced to a PCIe x16 slot on the IMB-Q354
motherboard. The PCIe x16 graphics card is then installed on the PCIe x16 slot on the
motherboard. The PCIe x16 edge connector is shown in Figure 2-12 .
