Abstract
A system and circuitry is described for a programmable PCI/PCI-x bus that accepts PCI and PCI-x controller cards and associated IO devices. The operating speed of the bus is reduced in accordance with the number and speed of the device as prearranged. The speed is to assure that the IO devices and the bus controller are compatible. A mix of PCI and or PCI-x devices can be accommodated by the present invention. Moreover, for high speed devices, the physical length of the bus itself is changed to better accommodate the higher speeds involved.
