Program options dialog page "Global DOSBox settings"

This page will only be visible if the advanced setup mode is selected at the bottom of the program options dialog.

On this page you can configurate DOSBox settings which will be used for all set up DOSBox installations.

  • Minimize DFendX when DOSBox starts
    If this option is activated, the DFendX main window will minimize as soon as you start a DOSBox based profile.
    (Default value for this option: off)
  • Restore program window when DOSBox is closed
    This option can only be activated if "Minimize DFendX when DOSBox starts" is active. It will restore the DFendX main window as soon as the DOSBox instance you have started by starting some profile closes.
    (Default value for this option: off)
  • Use short path names for mount commands
    The DOSBox command line is limited to 134 characters, so long path names in mount commands can cause problems. With this option activated DFendX will create short path names in the DOSBox conf file ("PROGRA~1" instead of "Program files" for example) to keep the commands for mounting folders short.
    (Default value for this option: on)
  • Show warning messages on DOSBox path name translation errors
    Because DOSBox uses a different algorithm to make short path names than Windows, long path names need to be translated to the DOSBox version (for example for use in "cd" commands). If this option is activated you will get a warning message if this translation process fails.
    (Default value for this option: on)
  • Always create conf files for all profiles
    If this option is turned on, DFendX will create for each profile file (.prof) a DOSBox configuration file (.conf) in the "Confs" folder and keep this configuration file up to date. If this option is off, the DOSBox configuration files will only be generated on the fly when starting DOSBox. (The function to always create all configuration files is not available in portable operation mode.)
    (Default value for this option: off)
  • Show dialog to fix problems if DOSBox closes in less than this number of seconds
    If DOSBox terminates very quick after start it is very likely there is a problem starting DOSBox or starting the DOS program inside DOSBox. In this case DFendX can display a dialog with some options to solve the problem. In this field you can set up on what maximal DOSBox runtime the start up fix dialog will be shown.
    (Default value for this option: 3)
