After you choose a monitor and resolution, you must assign one or more console function keys (<F>) to them. This creates a link between the particular graphics adapter, monitor, and resolution, and the assigned function key, as described in ``About function keys and video configuration''
If you elected to specify function keys in the Function Key Setup window, you will see a Specify Function Keys window. When it appears, select the function key or keys you want to associate with the current adapter, monitor, and resolution, then click on OK.
If you are unsure about the current adapter and resolution, look in the ``Current selection'' field at the top of the window.
