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.
