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.
