Since IBM's CPC925 uses HyperTransport, they can use nForce south bridges.
This is a full blown computer folks. PCIe replaces both AGP and PCI/PCI-X. As you can see, this board supports PCI as well. PCIe is compatible (or rather identical) at the driver level. In fact NVidia's PCIe video cards are just their AGP 8X cards with a PCIe bridge, no change to the software was necessary.
They have various parters like Terra-Soft Solutions listed too. These are small companies. They seem to want to recruit more support from similar companies :-D :-D
