you do not have. Please see the &man.sio.4; manual page for
complete information on how to write configuration lines for
multiport boards. Be careful if you are using a configuration
you do not have in the case of FreeBSD&nbsp;4.X, for
FreeBSD&nbsp;5.X you have to edit your

Be careful if you are using a configuration
