     NetBSD includes a machine-independent PCI bus subsystem and several ma-
     chine-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.
