The information in this article applies to:

  • Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

The following information describes why Microsoft Windows does not implement an INT 15H handler to facilitate multitasking in the presence of a NetBIOS network.

Windows does not use the INT 15H handler at all. INT 15H is specific to the IBM PC/AT. Windows will never use an INT 15H handler because it is designed to work on a number of different OEM machines.
