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 is
not connected to any devices on the workstation board S5000XVN.
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 133MHz. With both Slot 1 and Slot 2
populated, Slot 2 supports a maximum speed of 100 MHz. PCI-X Slot 1 supports a maximum
speed of 100 MHz even when Slot 2 is not populated.
3.2.1.3
PE0: One x4 PCI Express* Bus Segment
One x4 PCI Express* bus segment is directed through the ESB2-E. This PCI Express* segment,
PE0, is routed to PCI Express* Slot 4.
3.2.1.4
PE1: One x4 PCI Express* Bus Segment
One x4 PCI Express* bus segment is directed through the ESB2-E. This PCI Express* segment,
PE1, is routed to PCI Express* Slot 3. This becomes a x8 PCI Express* bus segment for
workstation boards that do not support SAS by combining PE2 with PE1.
