 120           If you select this option you will also want to select at
 121           least one of the tape interface options and one of the tape
 122           hardware options in order to access a tape device.
 123           This option is also available as a module. The module will be
 124           called tape390 and include all selected interfaces and
 125           hardware drivers.
