31.58Sgmcgarry# GENERIC machine description file
41.58Sgmcgarry# 
51.58Sgmcgarry# This machine description file is used to generate the default NetBSD
61.58Sgmcgarry# kernel.  The generic kernel does not include all options, subsystems
71.58Sgmcgarry# and device drivers, but should be useful for most applications.
81.1Sjonathan#
91.58Sgmcgarry# The machine description file can be customised for your specific
101.58Sgmcgarry# machine to reduce the kernel size and improve its performance.
111.58Sgmcgarry#
121.58Sgmcgarry# For further information on compiling NetBSD kernels, see the config(8)
131.58Sgmcgarry# man page.
141.58Sgmcgarry#
151.58Sgmcgarry# For further information on hardware support for this architecture, see
161.58Sgmcgarry# the intro(4) man page.  For further information about kernel options
171.58Sgmcgarry# for this architecture, see the options(4) man page.  For an explanation
181.58Sgmcgarry# of each device driver in this file see the section 4 man page for the
191.58Sgmcgarry# device.
