Reading the News groups it appears many people are surprised to find a riser slot and have no idea what it is for. Each Riser standard has a listing on this page which may provide additional technical information about the standard. The actual IC chip interface will depend on the bus interfacing to the Riser board.

The ACR slot was a competing specification developed by a group of third-party vendors.
Although their presence on many recent motherboards intrigues some upgraders, these slots were never intended as general-purpose expansion slots. 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 were achieved only limited distribution. CNR also midem Plug and Play support So Riser implementations are only seen as deliverables from computer manufacturers, and not as up-grade cards in commercial stores. CNR slots modrm once commonly found on Pentium 4 -class motherboards, but have since been phased out in favor of on-board or embedded components.

Type A and Type B, each with different pin assignments. The same group also developed a physically smaller version, the MDC. All of them were designed to be used by OEM system builders, not by backyard mechanics.
Reading the News groups it appears many people are surprised to find a riser slot and have no idea what it is for. Additional description of Riser cards is also listed below. 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.

The AT Form Card page provides the pinout for this interface. With the integration of components such as ethernet and audio into the motherboard, the CNR is obsolete, and is not found on PC motherboards anymore. Nearly everything inside a PC is designed to be user-installable. Stay ahead with the world’s most movem technology and business learning platform.
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. Physically, a CNR slot has two rows of 30 pins, with two possible pin configurations: Views Read Edit View history.
