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*, ...
