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.
