because things that make sense under DOS don't necessarily under OS/2. Any
direct hardware call for example, typically has to go thru OS/2' API. Imagine
you write a programme under dos that takes control of the sound blaster
buffer, reads a sound file a shove it down the buffer to be played. This works 
beautifully under dos, and will get you back to the prompt for work while the
music plays. You can do that under DOS because you own the machine. You can't
do that under OS/2 because some other program might already be using the sound 
card.
