Motherboard with separate PCI buses

I am trying to find a motherboard with two separate PCI buses. This is required for bandwidth reasons, a single PCI bus with multiple interfaces is not suitable.

Any information on motherboards, chipsets etc that provide this would be much appreciated.

  1. PCI is a shared bus. There are none (that I know of anyways) that have two separate buses. Use PCIe instead.

    What are you trying to do? What you ask doesn't make a lot of sense.
  2. We have legacy specialised (read expensive) PCI hardware in separate boxes and are looking for a motherboard solution that would enable us to put them in the same box(synchronisation and control reasons) .

    Each card, when flooded, will require upwards of 90% of the PCI bandwidth. Therefore, we are looking for a solution which has multiple buses.

    Using PCIe instead isn't really helpful as we are dealing with legacy hardware..
  3. Ok, so your need is real. I was only checking...

    The PCI bus connects to the Southbridge in old motherboards, MCH I think they call it now. I don't know of any boards that have two of these. I think the question now is which is the better idea/costs less. Keep the boxes separate, or buy new expensive machines.
