is a riser card specification to replace the
that supports V.90 analog modem, multi-channel
audio, and phone-line based networking. Because the CPU computing power is getting stronger, the digital processing job can
be implemented in main chipset and share CPU power. The analogy conversion (
) 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. 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.
