Multiple PCI adapters within single PCI slot on an matax planar

A method for supporting multiple PCI adapter cards in a single PCI slot in a computer system, the method comprising:

• providing a riser card for multiple PCI adapter cards in a PCI slot of an μATX planar;
• supporting individual signaling for the multiple PCI adapter cards based on at least a pair of bus signals of the PCI slot, including providing separate clock signals to each of the multiple PCI adapter cards;
• and
• utilizing the multiple PCI adapter cards through the PCI slot.
