MS-DOS versions are abandoned because of Y2K issues and lack of continued demand.

Issued at the same time as the GUI-only America Online began to grow in popularity, CIM was available for MS-DOS (" DOSCIM "), Microsoft Windows (" WinCIM "), Macintosh (" MacCIM "), and OS / 2 (" CIM for OS / 2 ") and allowed access to CompuServe's features, such as its forums, chat, e-mail, and messaging facilities ; these continued to be accessible via standard communications software using alphanumeric shortcuts.

They could be run from MS-DOS, executing Windows for the duration of their activity, and closing down Windows upon exit.

" Windows Me was the last operating system to be based on the Windows 9x ( monolithic ) kernel and MS-DOS.

Due to their higher prices, they never became very popular and PC-DOS ( IBM-DOS ) or MS-DOS came to be the dominant operating system.

The problems led to Bill Gates famously referring to the 80286 as a " brain dead chip ", since it was clear that the new Microsoft Windows environment would not be able to run multiple MS-DOS applications with the 286.

Later, this team would be placed by Softdisk in charge of a new, but short-lived, bi-monthly game subscription product called Gamer's Edge for the IBM PC ( MS-DOS ) platform.

The SL and TL were also shipped with MS-DOS 3. 3 and DeskMate 3 in ROM, and featured an EEPROM memory chip to store BIOS settings ( which enabled similar functionality to today's CMOS NVRAMs, so that startup options could be saved ).

Microsoft's intention was that application writers would write to the application programming interfaces in MS-DOS or the firmware BIOS, and that this would form what would now be termed a hardware abstraction layer.

There was no Microsoft-branded MS-DOS: MS-DOS could not be purchased directly from Microsoft, and each OEM release was packaged with the trade dress of the given PC vendor.

For example, PE / COFF headers still include an MS-DOS executable program, which is by default a stub that displays the simple message " This program cannot be run in DOS mode " ( or similar ).

Digital Research threatened legal action, claiming PC DOS / MS-DOS to be too similar to CP / M.

Normally in the MS-DOS operating system, only one program can be running at any given time, and when it wants to stop running, it relinquishes the control to DOS's shell program, < tt > COMMAND. COM </ tt >, using the system call < tt > INT 21H / 4CH </ tt >.

All VGA timings can be varied widely by software that bypasses the VGA firmware interface and talks directly to the VGA hardware, as many MS-DOS based games did.

" It's a richer medium than MS-DOS, and if we have a hot product in the Mac market, it will be easier to get into the PC market.

The first 16-bit system was CP / M-86, which was to be unsuccessful in competition with MS-DOS.

This is a legacy of MS-DOS, which only allowed a 128-byte command line to be passed to an application, making wildcarding by the DOS command prompt impractical.

The compiler is highly portable, and is known to be run on AmigaOS, BeOS, HP-UX 9, Linux, BSD, Mac OS X, Solaris, Win32, Win16 and MS-DOS.

The integrated development environment could run a BASIC program internally for traditional BASIC debugging ( see sample below ), or generate an MS-DOS stand-alone executable file that could be run on other systems without the Turbo Basic product or runtime libraries.

The MSX-DOS disk operating system had internal software mechanisms much like CP / M ( so CP / M software could be ported reasonably easy ), but had a file system compatible with MS-DOS, and its user commands were also similar to early MS-DOS versions.

CP / M-86 and MS-DOS had very similar functionality, but were not compatible as the system calls for the same function and program file formats were different, so two versions of the same software had to be produced and marketed to run under both operating systems.

Initially MS-DOS and CP / M-86 also ran on computers not necessarily hardware-compatible with the IBM PC such as the Apricot and Sirius, the intention being that software would be independent of hardware by making standardised operating system calls to a version of the operating system custom tailored to the particular hardware.

On an MS-DOS computer, the game can be copied to the hard-disk drive.

Brain is the industry standard name for a computer virus that was released in its first form in January 1986, and is considered to be the first computer virus for MS-DOS.

This capability was most frequently used to read MS-DOS disks.

Since it was included with most versions of MS-DOS, it was also a low cost way for many would-be programmers to learn the fundamentals of computer programming.

Much of its success was because Windows 3. 0 ( along with MS-DOS ) was bundled with most new computers.

Unlike most PC clones, several Tandy 1000 computers had MS-DOS built into ROM and could boot in a few seconds.

MS-DOS did not have an API for graphics, and the BIOS only included the most rudimentary of graphics functions ( such as changing screen modes and plotting single points ).

The ' terminate and stay resident ' method was used by most MS-DOS viruses which could either take control of the PC or stay in the background.

), CP / M, and most recently by Microsoft's MS-DOS, has been very controversial with Mac users.

Unlike most BASIC implementations of this period, Turbo Basic was a full compiler which generated native code for MS-DOS.

Because it is the primary means of displaying the files and directories on disk or other storage medium within a command window, the dir command is one of the most basic commands employed by users of the command line interface to MS-DOS and subsequent versions of Microsoft Windows.

Although UUCP was originally developed on Unix and is most closely associated with Unix-like systems, UUCP implementations exist for several non-Unix-like operating systems, including Microsoft's MS-DOS, Digital's VAX / VMS, Commodore's AmigaOS, classic Mac OS, and even CP / M.

The Apple II version was the most popular format, the PC / MS-DOS came in a close second, and the Commodore 64 / 128 got the fewest votes.

The most enduring element of 86-DOS was its primitive line editor, EDLIN, which remained the only editor supplied with Microsoft versions of DOS until the June 1991 release of MS-DOS 5. 0, which included a TUI-based editor, MS-DOS Editor based on QBasic.

In the early days of personal computers, before hard drives became commonplace, most fully outfitted computer systems had 2 floppy drives addressed as A: and B: on CP / M and MS-DOS.

Even plain text computer files are not free from this problem — e. g. under MS-DOS, most programs could not work correctly with UNIX-style text files ( see newline ), and for non-English speakers, the different code pages always have been a source of trouble.

It was originally released in 1990 for internal and external mail on Netware networks with MS-DOS clients, and was subsequently ported to Microsoft Windows, which became the most widely used version.

To simplify these tasks, most disk cloning programs can run under an operating system different from the native operating system of the host computer, for example, MS-DOS or an equivalent such as PC-DOS or DR-DOS, or Linux.

It supports only printers that can connect via a parallel printer port, such as most HP Deskjets and which can run under MS-DOS ; it does not support printers that require a USB connection or are labelled " Windows only ".

It was the most popular memory manager for the MS-DOS and other DOS operating systems.

Since Windows 3. 1 and earlier was merely a graphical interface for MS-DOS, most text applications that ran on earlier Windows versions were actually MS-DOS applications running in " DOS boxes ".

Rampage was ported to most home computers and video game consoles of its time, including the Atari 2600, Atari 7800, Atari Lynx, Atari 8-bit, Atari ST, Commodore 64, MS-DOS / IBM PC, ZX Spectrum, Amstrad CPC, NES, and Sega Master System.

Doom is one of the most widely ported video games in the first-person shooter genre: starting with the original MS-DOS version ( released as shareware on December 10, 1993 ), it has been released officially for a number of computer operating systems, video game consoles, handheld game consoles, and other devices.
