**86Box** is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.

Features
--------

* Easy to use interface inspired by mainstream hypervisor software
* Low level emulation of 8086-based processors up to the Mendocino-era Celeron with focus on accuracy
* Great range of customizability of virtual machines
* Many available systems, such as the very first IBM PC 5150 from 1981, or the more obscure IBM PS/2 line of systems based on the Micro Channel Architecture
* Lots of supported peripherals including video adapters, sound cards, network adapters, hard disk controllers, and SCSI adapters
* MIDI output to Windows built-in MIDI support, FluidSynth, or emulated Roland synthesizers
* Supports running MS-DOS, older Windows versions, OS/2, many Linux distributions, or vintage systems such as BeOS or NEXTSTEP, and applications for these systems

Minimum system requirements and recommendations
-----------------------------------------------

* 64-bit Intel Core 2, AMD Athlon 64 or ARMv8 processor or newer
* 4 GB of RAM or higher
* **Windows version:** Windows 7 Service Pack 1 or newer on Intel/AMD systems; Windows 11 or newer on ARM systems
* **Linux version:** Ubuntu 16.04, Debian 9.0 or other distributions from 2016 onwards
* **macOS version:** macOS 10.14 Mojave or newer

Performance may vary depending on host and guest configuration. Most emulation logic is executed in a single thread. Therefore, systems with greater IPC (instructions per clock) capacity should be able to emulate higher clock speeds.

For easier handling of multiple virtual machines, use a manager application:

* [Avalonia 86](https://github.com/notBald/Avalonia86) by [notBald](https://github.com/notBald) (Windows and Linux)
* [86Box Manager](https://github.com/86Box/86BoxManager) by [Overdoze](https://github.com/daviunic) (Windows only)
* [86Box Manager X](https://github.com/RetBox/86BoxManagerX) by [xafero](https://github.com/xafero) (Cross platform Port of 86Box Manager using Avalonia)
* [sl86](https://github.com/DDXofficial/sl86) by [DDX](https://github.com/DDXofficial) (Command-line 86Box machine manager written in Python)
* [Linbox-qt5](https://github.com/Dungeonseeker/linbox-qt5) by [Dungeonseeker](https://github.com/Dungeonseeker/) (Linux focused, should work on Windows though untested)
* [MacBox for 86Box](https://github.com/Moonif/MacBox) by [Moonif](https://github.com/Moonif) (MacOS only)

To use 86Box on its own, use the `--vmpath`/`-P` command line option.
