      3 # GENERIC machine description file
      4 # 
      5 # This machine description file is used to generate the default NetBSD
      6 # kernel.  The generic kernel does not include all options, subsystems
      7 # and device drivers, but should be useful for most applications.
      8 #
      9 # The machine description file can be customised for your specific
     10 # machine to reduce the kernel size and improve its performance.
     11 #
     12 # For further information on compiling NetBSD kernels, see the config(8)
     13 # man page.
     14 #
     15 # For further information on hardware support for this architecture, see
     16 # the intro(4) man page.  For further information about kernel options
     17 # for this architecture, see the options(4) man page.  For an explanation
     18 # of each device driver in this file see the section 4 man page for the
     19 # device.
