For a 286 I would run FreeDos with a copy of Gem for a GUI when I want it. FreeDos has alot more modern support for hardware, networking, etc. All DOS programs work on it, uses almost no memory with mouse support.
Gem is a GUI like windows that run does programs and a bunch of great programs made for it. It runs great on a 286 and has alot more moderm support in drivers then 3.11
