PCI Slots Specification
The PCI specification allows for three different PCI add-on cards : 3.3V,5V and
“Universal adapters” , but only 3.3V signaling is allowed for 66MHz or greater PCI
devices .Please check the specification of the PCI devices before using any of them.
Meanwhile, be sure about the specification of the PCI Device (Golden Fingers) could
meet our design of PCI/ PCI-X architecture for ROBO-8716VG2A. The below
picture shows the PCI Slot Pin definition. (Figure 5-2 & 5-3)

P4 Power connector
ROBO-8716VG2A requires power drawing from the 12V connector. The CPU
supplementary power connector should be connected at all time for this P4 system to
run properly. If the system’s main power comes from a backplane, the CPU
supplementary power connector should still be connected.
