This article presents a list of commands used by MS-DOS compatible operating systems, especially as used on IBM PC compatibles. Many unrelated disk operating systems use the DOS acronym and are not part of the scope of this list. In MS-DOS, many standard system commands are provided for common tasks such as listing files on a disk or moving ...
MS-DOS / PC DOS and some related disk operating systems use the files mentioned here. System Files: [1] IO.SYS (or IBMBIO.COM): This contains the system initialization code and builtin device drivers; MSDOS.SYS (or IBMDOS.COM): This contains the DOS kernel. Command-line interpreter (Shell): COMMAND.COM: This is the command interpreter.
Starting with Windows 10, the ability to create a MS-DOS startup disk has been removed, and so either a virtual machine running MS-DOS or an older version (in a virtual machine or dual boot) must be used to format a floppy disk, or an image must be obtained from an external source.
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 4, 2011, with originally ...
MSDOS.SYS is a system file in MS-DOS and Windows 9x operating systems. In versions of MS-DOS from 1.1x through 6.22, the file comprises the MS-DOS kernel and is responsible for file access and program management. MSDOS.SYS is loaded by the DOS BIOS IO.SYS as part of the boot procedure. [1] In some OEM versions of MS-DOS, the file is named MSDOS ...
When a user is logging on to Windows, the startup sound is played, the shell (usually EXPLORER.EXE) is loaded from the [boot] section of the SYSTEM.INI file, and startup items are loaded. In all versions of Windows 9x except ME, it is also possible to load Windows by booting to a DOS prompt and typing "win".
In the PC bootup sequence, the first sector of the boot disk is loaded into memory and executed. If this is the DOS boot sector, it loads the first three sectors of IO.SYS into memory and transfers control to it. IO.SYS then: Loads the rest of itself into memory. Initializes each default device driver in turn (console, disk, serial port, etc ...
Different operating systems use different boot disk contents. All boot disks must be compatible with the computer they are designed for. MS-DOS/PC DOS/DR-DOS. A valid boot sector in form of a volume boot record (VBR) IO.SYS or IBMBIO.COM; MSDOS.SYS or IBMDOS.COM; COMMAND.COM; All files must be for the same version of the operating system.
