Communications and networking riser CNR is a slot found on certain PC motherboards and used for specialized networking, audio, and telephony equipment. With the integration of components such as ethernet and audio into the motherboard, the CNR is obsolete, and is not found on PC motherboards anymore. Stay ahead with the world’s most comprehensive technology and business learning platform. The actual IC chip interface will depend on the bus interfacing to the Riser board. Each Riser standard has a listing on this page which may provide additional technical information about the standard. Views Read Edit View history.

Tech Flashback: AMR, CNR cards
Although their presence on many recent motherboards intrigues some upgraders, these slots were never intended as general-purpose expansion slots. Additional description of Riser cards is also listed below.
Nearly everything inside a PC is designed to be user-installable. Reading the News groups it appears many people are surprised to find a riser slot and have no idea what it is for. Physically, a CNR slot has two rows of 30 pins, with two possible pin configurations: Views Read Edit View history. Type A and Type B, each with different pin assignments.
Motherboard expansion slot Computer hardware stubs. For all other IC functions use the Components Icon below.
In most cases driver IC’s will be listed on one of those pages. Retrieved from ” https: Intel developed the AMR slot to provide an easy, standardized way to integrate modem and audio functions into finished systems at minimal cost, but OEM system builders ignored it in droves.
While a consumer would not up-grade using a Riser slot, opting for a Carrd slot implementation instead.
With the integration of components such as ethernet and audio into the motherboard, the CNR is obsolete, and is not found on PC motherboards anymore. The result was that, although some motherboards included an AMR slot, very few AMR-compatible cards were ever developed and those that were achieved only limited distribution. The ACR slot was a competing specification developed by a group of third-party vendors. So Riser implementations are only seen as deliverables from computer manufacturers, and not as up-grade cards cbr commercial stores.
The actual IC chip interface will depend on the bus interfacing to the Riser board.

This resulted in a quicker production-to-market time for new motherboards, and allowed mass-production of CNR cards to be used on multiple motherboards. However; many people are more concerned about cost with out regard for the number of PCI expansion slots, or whether the function is performed by the processor or some expansion card. CNR also adds Plug and Play support The Specification defines a hardware scalable Original Equipment Manufacturer OEM mother board riser and interface that supports the audio, modem, and local area network LAN interfaces of core logic chipsets.
You can help Wikipedia by expanding it. CNR slots were once commonly found on Pentium 4 -class motherboards, but have since been phased out in favor of on-board or embedded components. With Safari, you learn the way you learn best. Many see them as low cost cards using a slot that could have been a spare PCI slot.
