      3 # GENERIC machine description file
      4 # 
      5 # This machine description file is used to generate the default NetBSD
      6 # kernel.  The generic kernel on NetBSD/alpha does enough to get booted,
      7 # etc., but not much more.  For a more complete kernel see the ALPHA
      8 # machine description file.
      9 #
     10 # The machine description file can be customised for your specific
     11 # machine to reduce the kernel size and improve its performance.
     12 #
     13 # For further information on compiling NetBSD kernels, see the config(8)
     14 # man page.
     15 #
     16 # For further information on hardware support for this architecture, see
     17 # the intro(4) man page.  For further information about kernel options
     18 # for this architecture, see the options(4) man page.  For an explanation
     19 # of each device driver in this file see the section 4 man page for the
     20 # device.
     21 
     22 # If you add stuff to this, please add it to the ALPHA configuration, too.
