3.2.1 PCI Subsystem
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 following table 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 Subsystem
All 32-bit, 33-MHz PCI I/O is directed through the ESB2-E ICH6. The 32-bit, 33-MHz PCI
segment created by the ESB2-E-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, 133-MHz PCI Subsystem
One 64-bit PCI-X bus segment is directed through the ESB2-E ICH6. This PCI-X segment, PXA,
is routed to PCI-X Slots 1 and 2. With only one PCI-X adapter populated in Slot 2 and Slot 1 left
empty, PCI-X Slot 2 supports a maximum speed of 133 MHz. With both Slot 1 and Slot 2
populated, Slot 2 supports a maximum speed of 100MHz. PCI-X Slot 1 supports a maximum
speed of 100 MHz even when Slot 2 is not populated.
