86Box is an open-source, low-level PC emulator. It focuses on PC hardware from the 80s and 90s. A variety of operating systems can be installed in the emulator, which can then be used to launch programs. It is a fork of PCem. It took over from PCem-X after the latter was deprecated.
To run any program, an operating system needs to be installed in 86Box first. It has a dynamic recompiler that gives accurate Pentium/II support. It can also emulate numerous 2D and 3D cards.
86Box has now introduced a new GUI on Windows. This GUI is much more reminiscent of something like Virtual PC 2007 or VMware than the PCem UI, so users of those bits of software should feel more at home now.
- IMG (Raw floppy images)
- FDI (Both Japanese and stream)
- 86F (Battler's own format, more accurate than IMG, and handles almost any exotic thing you can throw at it.)
- IMG (Raw hard disk images)
- HDI (Japanese format, often used with PC-98 emulators)
- fixed size VHDs (Unofficially, handled as an IMG. Usually works.)
- Mounting a real or virtual CD-ROM drive
An incomplete list of operating systems that can be installed on it:
- Microsoft Windows versions up to Windows XP (including pre-reset Windows Longhorn builds and Windows Vista build 3790.1232)
- Select any IA-32 flavor of NT before Vista, it works.
- Any flavor of Linux that supports the original Pentium
- Minix-PC 1.x, 2.x
- BSD (Only FreeBSD 6.x and OpenBSD i386 tested, NetBSD/i386 has some boot issue.)
- NEXTSTEP 3.1 to 3.3, OPENSTEP 4.0 to 4.2 (including Apple Rhapsody developer releases)

- Western Digital WD8003 series for ISA and MCA.
Network cards can use either WinPcap or SLiRP support on the host system, where WinPcap allows for a full network stack, but requires an installation of the WinPcap software on that system, or SLiRP, which basically implements a simple TCP and UDP packet forwarding system based on PAT. This mode does not require additional software to be installed but is limited to basic TCP and UDP based protocols.
The recently re-designed configuration user interface allows for easy configuration of either mode.
