Rufus was originally designed [5] as a modern open source replacement for the HP USB Disk Storage Format Tool for Windows, [6] which was primarily used to create DOS bootable USB flash drives. The first official release of Rufus, version 1.0.3 (earlier versions were internal/alpha only [ 7 ] ), was released on December 04, 2011, with originally ...
A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Although Windows XP could emulate DOS, it could not run many of its applications as they ran only in real mode to directly access the computer's hardware, and Windows XP's protected mode prevented such ...
With Windows 95, 98, and Me, the role of MS-DOS was reduced to a boot loader according to Microsoft, with MS-DOS programs running in a virtual DOS machine within 32-bit Windows, with ability to boot directly into MS-DOS retained as a backward compatibility option for applications that required real mode access to the hardware, which was ...

A live CD or live DVD is a CD-ROM or DVD-ROM containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive.
Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
Originally MS-DOS was designed to be an operating system that could run on any computer with a 8086-family microprocessor.It competed with other operating systems written for such computers, such as CP/M-86 and UCSD Pascal.
OS/2 allows for 'DOS from Drive A:', (VMDISK). This is a real DOS, like MS-DOS 6.22 or PC DOS 5.00. One makes a bootable floppy disk of the DOS, adds a number of drivers from OS/2, and then creates a special image. The DOS booted this way has full access to the system, but provides its own drivers for hardware.
