A dual bus interface PCB includes a main chipset component, a first type bus interface connector, and a second type bus interface connector. The PCB can be configured at fabrication time to enable a variety of configurations for operation. Optionally, the PCB can also be provided at least one memory chip and a NIC (Network Interface Card) chip. By virtue of having a dual interface, the PCB can be used with either the first type or the second type bus. Furthermore, the dual interface PCB eliminates the need by chipset manufacturers to carry multiple PCB variations of the same product in order to support various bus interfaces. In one embodiment, the PCB is a dual PCI-X/PCI-E interface PCB.
