 pc speaker and interrupt


>is it possible to 'beep' by using interrupt ?

Yes... and there are many different ways...

Probably the easiest way is the write the "BELL" or "ALERT" character

mov     ah, 02h
mov     dl, 07h
int     21h

The above will output the bell character... under Windows it actually
plays a .wav file (MS got funky...)
