ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of computer systems. More specifically, the present invention relates to electrical signals that are transmitted onto and off of a motherboard of a computer system.
BACKGROUND OF THE INVENTION
Video playback, enhanced graphics, and extended audio connectivity are becoming the standard hardware building blocks to support multimedia. To achieve cost savings, these features are being integrated onto the motherboard. Sound and graphics add-in cards that were once required to support multimedia functionalities are now being integrated onto the motherboard in the form of specialized application specific integrated circuits (ASICs) and in other instances are being brought into the processor itself. To achieve this integration, multimedia outputs need to be transmitted off the motherboard and multimedia inputs need to be transmitted onto the motherboard. Specifically, it is desirable to bring audio connectors, Universal Serial Bus connectors, as well as other indicators and switches to the front panel of a computer system chassis. The front panel of the computer system chassis is a location that is most accessible to the computer user. However, with today's form factors, it is a challenge to bring more input/output (I/O) connectivity out of the chassis and to the front panel.
One approach to bringing audio and video I/O out of the chassis in the past was to use cables to connect motherboard components to connectors mounted on spare expansion slots on the chassis. This approach had several disadvantage. First, the use of cables incurred additional costs. Second, cabling the motherboard components to connectors required additional time and resources from the manufactures.
SUMMARY
A riser card for use in a chassis according to a first embodiment of the present invention is disclosed. The riser card includes a body having a first end and a second end. The length of the body is adequate to simultaneously allow the first end and the second end to be proximately situated at a back and a front wall of the chassis respectively. The riser card also includes a female edge connector disposed on the body that receives a male edge connector of a motherboard.
