The drivers are sorted into categories. Expand an item in the tree on the left to view the drivers. When you select a driver in the tree on the left, you will see more information on the right for that driver.
For most drivers, except for those which won't accept parameters, you can change the parameters in the parameters field.
For several drivers, easy-to-use configuration dialogs have been added as well. If the "Configure" button is enabled, you can press it to have a configuration dialog for the parameters of the currently selected drivers. Such a configuration dialog will then change the "Parameters" entry field for you.
You have to press "Apply" to update the &cfgsys; line with the
new parameters -- either if you have changed the "Parameters" field yourself
or if you have used a configuration dialog. Pressing "Apply" will only modify
the one line in &cfgsys; with the currently selected driver. If you select
another driver, your configuration gets lost.
