MS-DOS itself primarily relied on just one configuration file, CONFIG.SYS. This was a plain text file with simple key–value pairs (e.g. DEVICEHIGH=C:\DOS\ANSI.SYS) until MS-DOS 6, which introduced an INI-file style format.
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.
In DOS, CONFIG.SYS is located in the root directory of the drive from which the system was booted. The filename is also used by Disk Control Program (DCP), an MS-DOS derivative by the former East-German VEB Robotron. [1] Some versions of DOS will probe for alternative filenames taking precedence over the default CONFIG.SYS filename if they exist:
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 ...
Most DOS .sys files are real mode device drivers. [1] Certain files using this extension are not, however: MSDOS.SYS and IO.SYS are core operating system files in MS-DOS and Windows 9x. CONFIG.SYS is a text file that contains various configuration options and specifies what device drivers will be loaded. [2] [3]
MSConfig (officially called System Configuration in Windows Vista, Windows 7, Windows 8, Windows 10, or Windows 11 and Microsoft System Configuration Utility in previous operating systems) is a system utility to troubleshoot the Microsoft Windows startup process.
Loads the DOS kernel and calls its initialization routine. The kernel is stored in MSDOS.SYS with MS-DOS and in IO.SYS with Windows 9x. At this point, "normal" file access is available. Processes the MSDOS.SYS file with Windows 9x. Processes the CONFIG.SYS file, in MS-DOS 2.0 and higher and Windows 9x.
It then loaded WIN100.BIN or WIN200.BIN and WIN100.OVL or WIN200.OVL, along with the configuration settings file WIN.INI. The default shell is the MS-DOS Executive . The modules GDI.EXE , KERNEL.EXE and USER.EXE , fonts, and the various device drivers (such as COMM.DRV , MOUSE.DRV , KEYBOARD.DRV ) are incorporated in WIN100.BIN / WIN200.BIN and ...
