The boot screen and command-line interface of MS-DOS 6, with an example of its directory structure The boot screen and command-line interface of FreeDOS, showing version information and an example of its directory structure. DOS (/ d ɒ s /, / d ɔː s /) is a family of disk-based operating systems for IBM PC compatible computers. [1]
Windows XP contains a copy of the Windows Me boot disk, stripped down to bootstrap only. This is accessible only by formatting a floppy as an "MS-DOS startup disk". Files like the driver for the CD-ROM support were deleted from the Windows Me bootdisk and the startup files (AUTOEXEC.BAT and CONFIG.SYS) no longer had content. This modified disk ...
Each computer would have its own distinct hardware and its own version of MS-DOS, a situation similar to the one that existed for CP/M, with MS-DOS emulating the same solution as CP/M to adapt for different hardware platforms. So there were many different original equipment manufacturer (OEM) versions of MS-DOS for different hardware. But the ...
FreeDOS 1.1, released on 2 January 2012, [12] is available for download as a CD-ROM image: a limited install disc that only contains the kernel and basic applications, and a full disc that contains many more applications (games, networking, development, etc.), not available as of November 2011 but with a newer, fuller 1.2.

In other words, Phar Lap created an OS/2 compatibility box for DOS. A 16-bit protected-mode DOS application can be built by compiling it with Microsoft C under DOS, specifying that an OS/2 program should be built, and then executing the resulting file on DOS with the aid of 286|DOS-Extender. With Lotus and Microsoft using DOS extenders, an ...
DR-DOS 7.07 (with BDOS 7.4/7.7) by Paul introduced new bootstrap loaders and updated disk tools in order to combine support for CHS and LBA disk access, the FAT12, FAT16 and FAT32 file systems, and the differing bootstrapping conventions of DR-DOS, PC DOS, MS-DOS, Windows, REAL/32 and LOADER into a single NEWLDR MBR and boot sector, so that the ...
More importantly, the DOS system, which handles files and disk partitioning, manages the disk storage system. [10] Moreover, while IO.SYS is the kernel file of MS-DOS 7, JO.SYS is an alternate filename for IO.SYS that is used for "specific purposes" in MS-DOS 7. JO.SYS supports booting from a CD-ROM drive or a hard disk. [14]
