Usage

name

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.

-exit

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.

-fullscreen

Starts DOSBox in fullscreen mode.

-userconf

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.

-startmapper

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

-noautoexec

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

-securemode

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

Notes

• 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.

Example

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.
