The generic kernel does not include all options, subsystems 71.116Sgmcgarry# and device drivers, but should be useful for most applications. 81.1Stsubai# 91.116Sgmcgarry# The machine description file can be customised for your specific 101.116Sgmcgarry# machine to reduce the kernel size and improve its performance. 111.116Sgmcgarry# 121.116Sgmcgarry# For further information on compiling NetBSD kernels, see the config(8) 131.116Sgmcgarry# man page. 141.116Sgmcgarry# 151.116Sgmcgarry# For further information on hardware support for this architecture, see 161.116Sgmcgarry# the intro(4) man page. For further information about kernel options 171.116Sgmcgarry# for this architecture, see the options(4) man page.
