5 1.58 gmcgarry # This machine description file is used to generate the default NetBSD
6 1.58 gmcgarry # kernel. The generic kernel does not include all options, subsystems
7 1.58 gmcgarry # and device drivers, but should be useful for most applications.
8 1.1 jonathan #
9 1.58 gmcgarry # The machine description file can be customised for your specific
10 1.58 gmcgarry # machine to reduce the kernel size and improve its performance.
11 1.58 gmcgarry #
12 1.58 gmcgarry # For further information on compiling NetBSD kernels, see the config(8)
13 1.58 gmcgarry # man page.
14 1.58 gmcgarry #
15 1.58 gmcgarry # For further information on hardware support for this architecture, see
16 1.58 gmcgarry # the intro(4) man page. For further information about kernel options
17 1.58 gmcgarry # for this architecture, see the options(4) man page. For an explanation
18 1.58 gmcgarry # of each device driver in this file see the section 4 man page for the
