Primary PCI Segment
The Primary PCI Segment is a 64-bit/133MHz PCI-X bus. There are three major devices located on
the Primary PCI Segment:
1.
AMCC 440GX processor. - This device has a built in arbiter which is used to arbitrate the
Primary PCI Segment.
2.
QLOGIC ISP2312 Dual FC Controller.
3.
PCI6540 PCIX-to-PCIX bridge (via its primary side).
