I haven't tested to compile as I am to lazy to setup a build environment, the older the software the harder it seams to get the build environment. No idea if it needs some dependencies or so.

Uhm, as I am only using MS-DOS 7.1 due to FAT32 I've forgotten that msdos.sys is only a text file in 7.1 but was a code file in 6.22. -mr ------------------------------------------------------------------------------ _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
