SWATVXD -- A Debugger for WIN386

The SWATVXD.EXE file is the accompanying VxD to 386SWAT. As long as it is in the same directory as the debugger file (386SWAT.LOD), it is loaded automatically by 386SWAT. If for some reason you don't wish that to happen, using the command WIN NOSWAT prevents the VxD from loading.

Switches

The VxD provides Windows services for 386SWAT, and is useful for debugging VxDs.

The VxD's operation is controlled by various switches all of which appear in the [386SWAT] section of your SYSTEM.INI file:

Debugging VxDs

To debug VxDs at their entry points, use the following switches:

VxD Filenames

Some VxD filenames, DDB names, Device_ID, and their switches:
