- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1
- - Microsoft Windows NT Advanced Server, version 3.1

-
- Typically, an MS-DOS-based multimedia application writes directly to
- the I/O ports of an installed sound adapter to perform audio
- functions. To support system security in Windows NT, an application
- cannot write directly to the hardware ports, it must write to a VDD
- (virtual device driver) that simulates the sound adapter. Currently,
- Windows NT does not include any VDDs for sound adapters; multimedia
- applications that perform direct I/O are not supported.
-
- Microsoft will post new information here in the Microsoft Knowledge
- Base as these modules are available to install in Windows NT.
