Yup, what he said… :-) If for some reason you actually need the release version number, starting with FreeDOS 1.2, under the %DOSDIR% the installer creates a VERSION.FDI file that contains that information. This assumes the user did not delete this file. Also, the boot configuration file (FDAUTO.BAT) sets an environment variable %OS_VERSION%. Which also assumes the user does not remove it. At present, there is no guaranteed method to get the “distro” release version. For the most part, it doesn’t matter all that much what “distro” release a user is running anyway. :-) Jerome _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
