3.2.1 PCI Sub-system
The primary I/O buses for the server board are PCI, PCI Express*, and PCI-X*, with six independent PCI
bus segments. The PCI buses comply with the PCI Local Bus Specification, Revision 2.3. The table
below lists the characteristics of the PCI bus segments. Details about each bus segment follow the table.

3.2.1.1 PCI32: 32-bit, 33-MHz PCI Bus Segment
All 32-bit, 33-MHz PCI I/O is directed through the ESB-2 ICH6. The 32-bit, 33-MHz PCI segment created
by the ESB-2-ICH6 is known as the PCI32 segment. The PCI32 segment supports the following
embedded devices:
• 2D Graphics Accelerator: ATI* ES1000 Video Controller
3.2.1.2 PXA: 64-bit, 133MHz PCI-X* Bus Segment
One 64-bit PCI-X* bus segment is directed through the ESB-2 ICH6. This PCI-X segment, PXA, can
support up to three add-in cards on a riser card plugged into the full height riser card slot (J4F1).
3.2.1.3 PE1: One x4 PCI Express* Bus Segment
One x4 PCI Express* bus segment is directed through the ESB-2. This PCI Express segment, PE1,
supports the optional Active SAS Midplane IOP as used in supported Intel chassis for this server board.
3.2.1.4 PE2: One x4 PCI Express* Bus Segment
One x4 PCI Express* bus segment is directed through the ESB-2. This PCI Express segment, PE2,
supports one x4 PCI Express segment to the proprietary Intel
® I/O Expansion Module mezzanine
connector (J3B1).
