IMPORTANT: If using PCI cards on shared slots, make sure that the drivers sup-

port “Share IRQ” or that the cards do not need IRQ assignments. Conflicts will arise

between the two PCI groups that will make the system unstable or cards inoperable.

3.7.3 Communication and Networking Riser (CNR) Slot

This connector supports specially designed network, audio, or modem riser cards.

Main processing is done through software and controlled by the motherboard’s sys-

tem chipset. This provides upgradeable network, audio, and/or modem solutions at

an incredibly low cost.

NOTE: CNRs are not included with this motherboard.
