DOSEMU, stylized asdosemu, is acompatibility layer software package that enablesDOS operating systems (e.g.,MS-DOS,DR-DOS,FreeDOS) andapplication software to run atopLinux onx86-based PCs (IBM PC compatible computers).
It uses a combination ofhardware-assisted virtualization features andhigh-level emulation. It can thus achieve nearly native speed for 8086-compatible DOS operating systems and applications onx86 compatible processors, and forDOS Protected Mode Interface (DPMI) applications onx86 compatible processors as well as onx86-64 processors. DOSEMU includes an 8086 processor emulator for use with real-mode applications in x86-64long mode.
DOSEMU is only available forx86 andx86-64 Linux systems (Linux 3.15 x86-64 systems cannot enter DPMI by default. This is fixed in 3.16).[2]
DOSEMU is an option for people who need or want to continue to use legacy DOS software; in some cases virtualisation is good enough to drive external hardware such asdevice programmers connected to theparallel port. According to its manual, "dosemu" is a user-level program which uses certain special features of the Linux kernel and the 80386 processor to run DOS in a DOS box. The DOS box, relying on a combination of hardware and software, has these abilities:
NetWare and other network connectivity via built-in IPX and pktdrvr support /../ the dosemu-freedos binary package starts a DOS-"C:\>"-Drive 'out-of-the-box' in a normal user's $HOME directory and runs without any further configuration (no root rights needed)
