Starting I/O Drivers Automatically

I/O drivers are started by the I/O Control program through the Task Configuration dialog box. When you install an I/O driver, the I/O Control program is automatically added to the list of tasks.

If you remove the I/O Control program from the task list, you can add it back again. The table below shows you the command line parameters you can use to specify how I/O drivers start.
