DESCRIPTION
     Other pci attachments are machine-dependent and depend on the bus topol-
     ogy and PCI bus interface of your system.  See intro(4) for your system
     for details.

     NetBSD includes a machine-independent PCI bus subsystem and several
     machine-independent PCI device drivers.

     Your system may support additional PCI devices.  Drivers for PCI devices
     not listed here are machine-dependent.  Consult your system's intro(4)
     for additional information.

OPTIONS
        PCI_ADDR_FIXUP  Fixup PCI I/O and memory addresses.

                        Some i386 and amd64 BIOS implementations don't allo-
                        cate I/O space and memory space for some PCI devices
                        -- primarily BIOS in PnP mode, or laptops that expect
                        devices to be configured via ACPI.  Since necessary
                        space isn't allocated, those devices will not work
                        without special handling.

                        This option allocates I/O space and memory space
                        instead of relying upon the BIOS to do so.

                        If necessary space is already correctly assigned to
                        the devices, this option leaves the space as is.

        PCI_BUS_FIXUP   Fixup PCI bus numbering; needed for many cardbus(4)
                        bridges.

                        Each PCI bus and CardBus should have a unique bus num-
                        ber.  But some BIOS implementations don't assign a bus
                        number for subordinate PCI buses.  And many BIOS
                        implementations don't assign a bus number for Card-
                        Buses.

                        A typical symptom of this is the following boot mes-
                        sage:
                              cardbus0 at cardslot0: bus 0 device 0...
                        Please note that this cardbus0 has a bus number `0',
                        but normally the bus number 0 is used by the machine's
                        primary PCI bus.  Thus, this bus number for cardbus is
                        incorrect (not assigned).  In this situation, a device
                        located in cardbus0 doesn't show correct device ID,
                        because its bus number 0 incorrectly refers to the
                        primary PCI bus, and a device ID in the primary PCI
                        bus is shown in the boot message instead of the
                        device's ID in the cardbus0.

                        This option assigns bus numbers for all subordinate
                        PCI buses and CardBuses.

                        Since this option renumbers all PCI buses and Card-
                        Buses, all bus numbers of subordinate buses become
                        different when this option is enabled.

        PCI_INTR_FIXUP  Fixup PCI interrupt routing via PCIBIOS or ACPI.

                        Some i386 and amd64 BIOS implementations don't assign
                        an interrupt for some devices.

                        This option assigns an interrupt for such devices
                        instead of relying upon the BIOS to do so.

                        If a valid interrupt has already been assigned to a
                        device, this option leaves the interrupt as is.
