PCI Slot Connector

There are three PCI buses implemented on the baseboard. PCI segment A supports 5V 32-
bit/33MHz PCI, segment B supports 3.3V 64-bit/100MHz PCI-X, and segment C supports 3.3V
64-bit/66MHz PCI operation. All segments support full-length PCI add-in cards. The pin-out for
each segment is below.
