Hello everyone. I have a Dell laptop from the early 2000s that I'm hoping to refit into a nostalgia machine. My plan is to install Windows ME with Real DOS mode enabled so that I can play classic games the way they were meant to be played (without emulation.) Is it possible to reasonably secure this machine? I probably won't be doing extensive/dangerous web surfing with it. It doesn't need to be absolutely bulletproof, just wondering if there's a fairly good free firewall compatible with it.
