3# GENERIC machine description file
4# 
5# This machine description file is used to generate the default NetBSD
6# kernel.  The generic kernel on NetBSD/alpha does enough to get booted,
7# etc., but not much more.  For a more complete kernel see the ALPHA
8# machine description file.
9#
10# The machine description file can be customised for your specific
11# machine to reduce the kernel size and improve its performance.
12#
13# For further information on compiling NetBSD kernels, see the config(8)
14# man page.
15#
16# For further information on hardware support for this architecture, see
17# the intro(4) man page.  For further information about kernel options
18# for this architecture, see the options(4) man page.  For an explanation
19# of each device driver in this file see the section 4 man page for the
20# device.
21
22# If you add stuff to this, please add it to the ALPHA configuration, too.
