Command Line Parameters

dosbox [name] [-exit] [-c command] [-fullscreen] [-userconf] [-conf congfigfilelocation] [-lang languagefilelocation] [-machine machine type] [-noconsole] [-startmapper] [-noautoexec] [-securemode] [-scaler scaler | -forcescaler scaler] [-version] [-socket socket] [-editconf program] [-opencaptures program] [-printconf] [-eraseconf] [-erasemapper]


If name is a directory, DOSBox will mount the specified directory as the C drive.
If name is an executable, DOSBox will mount the directory of name as the C drive, and start executing name.

DOSBox will close itself when the DOS application "name" ends.

-c command
Runs the specified command before running name. Multiple commands can be specified. Each command should start with -c though. A command can be: an Internal Program, a DOS command or an executable on a mounted drive.

Starts DOSBox in fullscreen mode.

Start DOSBox with the options specified in "configfilelocation". Multiple -conf options may be present.

-conf configfilelocation
Start DOSBox with the options specified in configfilelocation. Multiple -conf options may be present.

-lang languagefilelocation
Start DOSBox using the language string specified in languagefilelocation.

-machine machinetype
Setup DOSBox to emulate a specific type of machine. Valid choices are: hercules, cga, ega, pcjr, tandy, svga_s3 (default) as well as the additional svga chipsets listed in the DOSBox configuration file. The machinetype affects the video card and the available sound cards.

-noconsole (Windows Only)
Start DOSBox without showing the console window, output will be redirected to stdout.txt and stderr.txt. This is useful if DOSBox crashes, since the error messages stored in stdout.txt and stderr.txt may help the developers fixing the problem.

Enter the mapper directly on startup. Useful for people with keyboard or joystick problems.

Skips the [autoexec] section of the loaded configuration file.

Same as -noautoexec, but adds -securemode at the bottom of AUTOEXEC.BAT (which in turn disables any changes to how the drives are mounted inside DOSBox).


  • If a name/ command/ configfilelocation/ languagefilelocation contains a space in it, put the whole name/ command/ configfilelocation/ languagefilelocation between quotes ("example").
  • In Windows you can also drag directories/files onto the DOSBox executable.


dosbox c:\atlantis\atlantis.exe -c "MOUNT D C:\SAVES"

This would mount c:\atlantis as c:\ and run atlantis.exe. Before it does that, it would first mount C:\SAVES as the D drive.
