Windows Me does not allow a computer to boot into a DOS Kernel by shutting down Windows Me; thus TSRs became useless on Windows Me. The Windows NT series (including Windows 2000 , Windows XP , and later) replaced DOS completely and run in protected mode or long mode (later 64-bit versions only) all the time, disabling the ability to switch to ...
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".
CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems.It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system's DOS BIOS (typically residing in IBMBIO.COM or IO.SYS) during boot.
IBM PC DOS and DR DOS use the file IBMBIO.COM for the same purpose; it in turn loads IBMDOS.COM. In Windows 9x, the IO.SYS not only contains the DOS BIOS, but also holds the DOS kernel, which previously resided in MSDOS.SYS. Under some conditions, Windows 9x uses the alternative filenames WINBOOT.SYS [4] or JO.SYS instead.
The Session Manager Subsystem is the first user-mode process started by the kernel. Once started it creates additional paging files with configuration data from HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management, [1] the environment variables located at the registry entry HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment, and DOS device mappings (e.g. CON ...
In this example of dual booting, the user chooses by inserting or removing the DVD from the computer, but it is more common to choose which operating system to boot by selecting from a boot manager menu on the selected device, by using the computer keyboard to select from a BIOS or UEFI Boot Menu, or both; the Boot Menu is typically entered by ...
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 ...
COMMAND.COM is the default command-line interpreter for MS-DOS, Windows 95, Windows 98 and Windows Me.In the case of DOS, it is the default user interface as well. [2] It has an additional role as the usual first program run after boot (init process), hence being responsible for setting up the system by running the AUTOEXEC.BAT configuration file, and being the ancestor of all processes.
