> PCI devices should be probed and attached last for they are they > are the most flexible to configure NO !!! PCI devices get their addresses assigned by the PCI BIOS before giving control to the primary boot loader. They can not easily be moved around, since there may be constraints that are only known to the BIOS! > and can share interrupts. Yes, that much is true. But they can't share interrupts with non-PnP devices, and the BIOS has arranged all things before the FreeBSD device probe gets a chance ... PCI devices are probed first, because they are assumed to have got assigned unique and non-conflicting addresses. Regards, STefan
