86Box

86Box (formerly PCem-X, PCem Experimental or PCem Unofficial) is a hypervisor and IBM PC system emulator based on PCem that specializes in running old operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus. It is developed by the SoftHistory collective lead by Battler.

Supported guest operating systems

 * MS-DOS and compatible operating systems

Emulated hardware

 * CPU: Any CPU from an 8086/8088 to a Pentium MMX 300 MHz is supported, including IDT/Cyrix/AMD variants. Select Pentium II processors are also available. A dynamic recompiler is available, optional for 486 and WinChip and mandatory for Pentium and later processors.
 * FPU: FPUs are emulated for all 486DX and higher machines. For 286/386 machines, a 287/387SX/387DX FPU can be emulated optionally. 8087 FPUs aren't supported yet.
