Yep, this has come up several times now (yet another thing to add to the ELManagers FAQ) -- not all PCI busses are getting enumerated and recognized for newer PCIe chipsets. Especially the up to 8 PCIe masters in nForce Pro 2200+2050, especially when there are also 2 more PCI-X channels c/o an AMD 8131 as well. Remember, all AGP, PCI-X and PCIe busses/channels are, virtually, enumerated as PCI logic. Today's new generation of PCIe or PCIe+PCI-X have literally 6, 8 or even 10+ virtual PCI busses/channels compared to only 2-4 of the legacy AGP+PCI with optional PCI-X or two. First off, get the absolute latest BIOS. Most issues do get resolved by it. Secondly, try booting with a combination of ACPI/PCI kernel parameters. Using "pci=bios" might solve the problem, especially if you have the latest BIOS. If you hit the archives regarding the Tyan S2895 (Thunder K8WE), you'll find the boot-time option that person used (I believe it was "pci=bios"?). -- Bryan J.
