Running Nonnative Applications in Windows 2000 Professional

The MS-DOS environment supports nearly all MS-DOS-based applications. Exceptions are those that make direct hardware calls. It is recommended that you test your applications to ensure that they will work.

MS-DOS-based applications that are known not to work on Windows 2000 are:

  • Task-switching APIs.

  • Block-mode device drivers.

  • Interrupt 2F dealing with DOSKEY program callouts (AX = 4800).

  • Microsoft CD-ROM Extensions ( mscdex command) functions 2, 3, 4, 5, 8, E, and F.

  • The Clipboard API ( int 2k and func 17 commands).

  • 16-bit virtual device drivers that require direct access to a hardware component.
