Communication and Networking Riser Slot(CNR)
The mainboard provides Communication and Networking Riser(CNR) interface which can
support audio and/or modem functions . Furthermore, it provides a LAN interface for network-
ing functions. What its superiority compared with AMR is being able to support plug-and-play
function. Mechanically the CNR shares a PCI slot, thus if a CNR card is not used,users can an
additional PCI slot which shares the same position on back panel with CNR.
By using an audio codec, the AC97 digital link on CNR provides for cost-effective, high-
quality, integrated audio on the platform.
Sound Connector (PC-PCI)
This connector provides a bridge between the mainboard and PCI sound card to deliver
sound compatibility under DOS real-mode environment.
