|
# GENERIC machine description file
|
|
#
|
|
# This machine description file is used to generate the default NetBSD
|
|
# kernel. The generic kernel does not include all options, subsystems
|
|
# and device drivers, but should be useful for most applications.
|
|
#
|
|
# The machine description file can be customised for your specific
|
|
# machine to reduce the kernel size and improve its performance.
|
|
#
|
|
# For further information on compiling NetBSD kernels, see the config(8)
|
|
# man page.
|
|
#
|
|
# For further information on hardware support for this architecture, see
|
|
# the intro(4) man page. For further information about kernel options
|
|
# for this architecture, see the options(4) man page. For an explanation
|
|
# of each device driver in this file see the section 4 man page for the
|
|
# device.
