Build Status

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.


  • Easy to use interface inspired by mainstream hypervisor software
  • Low level emulation of 8086-based processors up to the Pentium 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

  • Intel Core 2 or AMD Athlon 64 processor
  • Windows version: Windows 7 Service Pack 1, Windows 8.1 or Windows 10
  • Linux version: Ubuntu 16.04, Debian 9.0 or other distributions from 2016 onwards
  • macOS version: macOS High Sierra 10.13
  • 4 GB of RAM

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

It is also recommended to use a manager application with 86Box for easier handling of multiple virtual machines.

It is also possible to use 86Box on its own with the --vmpath/-P command line option.

Getting started

See our documentation for an overview of the emulator's features and user interface.


We operate an IRC channel and a Discord server for discussing 86Box, its development and anything related to retro computing. We look forward to hearing from you!
