lEEt/OS is a graphical shell and partially posix-compliant multitasking operating environment that runs on top of a DOS kernel. The latest version can be downloaded from this site. lEEt/OS is tested with FreeDOS 1.2 and ST-DOS, but it may also work with other DOS implementations. It can be compiled with Open Watcom compiler. 8086 binaries are also available from this site.

lEEt/OS also has its own DOS kernel, but it is still very experimental and unstable. For any real use it is recommended to use lEEt/OS on top of the FreeDOS kernel.
lEEt/OS is slowly but surely migrating from FreeDOS to ST-DOS, its own DOS kernel.

lEEt/OS is licensed with GPLv3 license.

This website should work with almost any browser that supports HTML version 3.2 or newer.
