Welcome to the EzDos Operating System

At Ezdos.net, we preserve the spirit of classic 16-bit computing and make it run seamlessly on today’s hardware. Each EzDos setup comes on a plug-and-play USB drive — just connect it, boot, and you’re instantly in the EzDos environment. When you’re done, simply unplug the drive and your computer returns to Windows or whatever system you use. Most EzDos software is completely free to use, with no limits — just pure retro power.
EzDos is a 1980s-style, bare-bones 16-bit operating system designed to be simple, transparent, and easy to understand. It’s built from the inside out, showing you how an OS works as you use it. The EzDos files are organized in a clear, step-by-step progression: starting from the absolute basics and building all the way up to an operating system capable of running hundreds of 16-bit software programs.
