Introduction: https://dosbox-x.com/wiki/Home

"Unlike DOSBox's original focus on DOS games, DOSBox-X gives more focus on general DOS emulation, with the eventual goal of being a complete DOS emulation package that covers all pre-2000 DOS and Windows 9x based system scenarios, including all types and manners of hardware that were made for DOS PCs of that time."
