Well, but depending on the environment, it might not be "the default", the interrupt can be hooked into and chained by other software, for example in virtual environments or when some multi-tasking software is involved. INT28h is always the proper and preferred way to do this. If it doesn't work for you, then there might be an other problem at hand...
