# GENERIC32_IP12 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.
#
#
# Currently this config file supports Personal IRIS 4D/2x (IP6/IP10),
# Personal IRIS 4D/3x (IP12) and Indigo R3k (IP12).
#
# Note that to load at beginning of memory, the kernel _must_ be under
# 3.5MB in size to avoid stomping on (or being stomped on by) the PROM.
