Run 16 bit program on 64 machine bit without dosbox

Solution 1:

It's definitely not possible on Windows, see the following MSDN article: http://support.microsoft.com/kb/896458

Any tool that will allow you to run a 16bit prog on a 64bit Windows system has to emulate a system, which is what DOSbox does.

The following works:

public class DosBoxCaller {
    public static void main(String[] args) {
        ProcessBuilder pb = new ProcessBuilder(
                "C:\\Program Files\\DOSBox-0.74\\DOSBox.exe",
                "-conf C:\\Users\\Y\\dosbox.conf");
        pb.directory(new File("C:\\Users\\Y"));
        pb.redirectErrorStream(true);
        try {
            Process p = pb.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

If this doesn't call DOSBox for you, then you're probably getting a path wrong and simply ignoring the exception that is being thrown. Also doublecheck that your conf option is valid, and use a modified copy of the fullfledged dosbox config (to be found at your user folder\Application Data\Local\DosBox, copy it to your favorite folder, then edit autoexec).

Solution 2:

There's an emulator which can run simple commandline DOS programs in Windows x64. It's called "MS-DOS Player for Win32-x64". The source is provided, so in theory you can implement missing functionality.
