Yes. It was originally used for passive probing, but for some video cards, we also need to write to the PCI config space. It would be better if most OSs provided an interface for doing this though. >> that in 2.2-current from about two months ago, and I know of some >> cases where the PCI bus probe seems to fail.

Send me the >information I asked for (verbose boot messages and >the information about the chip set, CPU and BIOS >you can easily get at), and I'll make it work. The machines I'm referring to are not running FreeBSD (usually they are running Linux). At least one of the PPro machines is using a fairly old revision of the Orion chipset. I'll see if I can get some more information about this. As another data point, the scanpci program distributed with XFree86 (which uses differnet PCI code) does detect the PCI bus on these machines, and after that has been run, the PCI code in the XFree86 servers works again.
