31.14Sgmcgarry# GENERIC machine description file
41.14Sgmcgarry# 
51.14Sgmcgarry# This machine description file is used to generate the default NetBSD
61.14Sgmcgarry# kernel.  The generic kernel does not include all options, subsystems
71.14Sgmcgarry# and device drivers, but should be useful for most applications.
81.1Smarcus#
91.14Sgmcgarry# The machine description file can be customised for your specific
101.14Sgmcgarry# machine to reduce the kernel size and improve its performance.
111.14Sgmcgarry#
121.14Sgmcgarry# For further information on compiling NetBSD kernels, see the config(8)
131.14Sgmcgarry# man page.
141.14Sgmcgarry#
151.14Sgmcgarry# For further information on hardware support for this architecture, see
161.14Sgmcgarry# the intro(4) man page.  For further information about kernel options
171.14Sgmcgarry# for this architecture, see the options(4) man page.  For an explanation
181.14Sgmcgarry# of each device driver in this file see the section 4 man page for the
191.14Sgmcgarry# device.
