CNR (Communication and Network Riser) Expansion SSlloott
CNR 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. Owing to CPU computing power getting stronger, the digital processing job can be implemented in main chipset and share CPU power. The analogy conversion (CODEC) circuit requires a different and separate circuit design, which is put on CNR card. This motherboard implements sound CODEC on board, but reserves CNR slot for the option of modem function. Note that you can still use PCI modem card. Please note that if you want to use CNR audio card on CNR slot, you must disable the sound output of CODEC from BIOS to prevent the CODEC from making out noises at the same time.
