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: CNR LAN is not supported if this version of the motherboard features
the Intel onboard LAN chipset.
A CNR is not included with this motherboard.
