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.
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. CONFIG.SYS was introduced with DOS 2.0. [nb 1]
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.
[2] [3] (For compatibility purposes with some DOS applications the IBMBIO.COM file name was briefly also used by the IBM version of OS/2 1.0, where it resembled the OS2BIO.COM file as used by Microsoft.) The file is located in the root directory of the bootable FAT-formatted drive/partition (typically C:\) and typically has the system, hidden ...

Apple DOS is the disk operating system for the Apple II computers from late 1978 through early 1983. It was superseded by ProDOS in 1983. Apple DOS has three major releases: DOS 3.1, DOS 3.2, and DOS 3.3; [2] each one of these three releases was followed by a second, minor "bug-fix" release, but only in the case of Apple DOS 3.2 did that minor release receive its own version number, Apple DOS ...
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. Loads COMMAND.COM (or other operating system shell if specified). Displays the bootsplash in Windows 9x.
The category DOS files deals with articles related to specific files used by members of the family of DOS compatible operating systems for IBM PC compatible computers, such as MS-DOS, PC DOS, DR DOS, Concurrent DOS, Multiuser DOS, REAL/32, FlexOS, Novell DOS, PalmDOS, OpenDOS, FreeDOS, RxDOS, PTS/DOS, S/DOS, ROM-DOS, Embedded DOS etc.
