Abstract
A computer system comprises a chip set having a PCI Express controller with a preset lane width, a PCI Express connector with a relative bigger lane width, and a PCI Express interfaced apparatus with the bigger lane width. In the system, only part of the contacts within the PCI Express connector is connected to the PCI Express controller while the other contacts are opened.
Claims14
A main board, comprising:
- a controller that qualifies for PCI Express Base Specification Revision 1.0a with a preset lane width;
- and
- a connector that qualifies for PCI Express Base Specification Revision 1.0a with a bigger lane width with respect to the controller, having a plurality of contacts utilized for connecting to an interfaced apparatus that qualifies for PCI Express Base Specification Revision 1.0a with the bigger lane width, wherein part of the contacts are electrically connected to the controller.
An electronic system comprising:
- a controller that qualifies for PCI Express Base Specification Revision 1.0a with a preset lane width;
- a connector that qualifies for PCI Express Base Specification Revision 1.0a with a bigger lane width with respect to the controller, having a plurality of contacts, wherein part of the contacts are electrically connected to the controller;
- and
- an interfaced apparatus that qualifies for PCI Express Base Specification Revision 1.0a with the bigger lane width, electrically connected to the controller through the connector.
A method of having an interface that qualifies for PCI Express Base Specification Revision 1.0a with a preset lane width to accept a an interfaced apparatus that qualifies for PCI Express Base Specification Revision 1.0a with a relative bigger lane width comprising the steps of:
- providing a circuit board with a bus adapting to the preset lane width formed thereon;
- assembling a controller that qualifies for PCI Express Base Specification Revision 1.0a with the preset lane width to a first end of the bus;
- and
- assembling a connector that qualifies for PCI Express Base Specification Revision 1.0a with the bigger lane width to a second end of the bus utilized for connecting to the interfaced apparatus that qualifies for PCI Express Base Specification Revision 1.0a with the bigger lane width, wherein part of contacts within the connector corresponding to the controller are connected to the bus.
