CNR (Communication and Network Riser) is a riser card specification to replace the
AMR (Audio / Modem Riser) that supports V.90 analog modem, multi-channel audio, and
phone-line based networking. This motherboard implements sound CODEC on board
(can be disabled in BIOS), but reserves CNR slot for the option of modem function. Note
that you can still use PCI modem card. And due to hardware limitation, if the
motherboard you purchased implements an optional Creative CT5880 Audio Controller,
then there will not be CNR expansion slot on your motherboard.
