Setting the default media values
set up options for each media device on your system
or add a new device:
You can add devices not supported by the Device Query Interface (DQI) by entering the device name (for example, /dev/rct0) and specifying the block and volume size.
To remove entries for a non-DQI media device, select it and click on Delete. (The Delete button will not work on DQI devices.)
To specify a different default media device, see ``Setting the default backup device''.
