For all other IC functions use the Components Icon below. Riser card used with ATX form factor mother boards. The result was that, although some motherboards included an AMR slot, very few AMR-compatible cards were ever developed and those that moeem achieved only limited distribution. Carv from ” https: The board size and pinout are also defined in the specification for the ATX series of motherboard form factor.

The modem is a WinModem. Each Riser standard has a listing on cardd page which may provide additional technical information about the standard. With the integration of components such as ethernet and audio into the motherboard, the CNR is obsolete, and is not found on PC motherboards anymore.
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. In most cases driver IC’s will be listed on one of those pages. 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.
