1# $NetBSD: GENERIC,v 1.105 2020/03/08 06:32:41 rin Exp $ 2# 3# GENERIC machine description file 4# 5# This machine description file is used to generate the default NetBSD 6# kernel. The generic kernel does not include all options, subsystems 7# and device drivers, but should be useful for most applications. 8# 9# The machine description file can be customised for your specific 10# machine to reduce the kernel size and improve its performance. 11# 12# For further information on compiling NetBSD kernels, see the config(8) 13# man page. 14# 15# For further information on hardware support for this architecture, see 16# the intro(4) man page. For further information about kernel options 17# for this architecture, see the options(4) man page. For an explanation 18# of each device driver in this file see the section 4 man page for the 19# device. 20 21# Supports Sun2 (2/120, 2/170, 2/50, ...) 22# Supports root on: sd*, ...
