Intel® Server Board SE7320VP2
DRAM row boundary (DRB) registers, nor does it require notification to the operating system
that anything has occurred in memory.
3.4
The I/O sub-system is made up of several components:
This section describes the function of each I/O interface and how they operate on the Server
Board SE7320VP2.
3.4.1
The primary I/O interface for the Server Board SE7320VP2 is PCI, with four independent PCI
bus segments.
The table below lists the characteristics of the four PCI bus segments.

I/O Sub-System
The E7320 MCH provides the PCI Express interface to the full-height riser slot, and the
PCI Express interface to one of the on-board Ethernet controllers.
The 6300ESB ICH provides the PCI-X interface to the full-height riser slot, low-profile
riser slot, and the PCI interface to the onboard video controller, super I/O chip, one of
the Ethernet controllers, and the management sub-system
One PCI 33MHz/32-bit bus segment (P32-A) is controlled through the 6300ESB ICH.
One PCI-X 66MHz/64-bit bus segment (P64-A) is controlled through the 6300ESB ICH.
One x4 PCI Express (P64-Express-A) bus segment is controlled from the E7320 MCH.
One x1 PCI Express (P64-Express-B) bus segment is controlled from the E7320 MCH.
