Whew, you will need hardware interrupts. As example, if you wanna use 
a SoundBlaster card you will have to hook your own SB-IRQ. Its number 
is usually 5, I think. The interrupt handler should be built like 
this:

SB_Int_Handler 
{
  Play_Data_In_Buffer1;
  Load_New_Data_In_Buffer2;
  Swap_The_Buffer_Pointers;
}

The idea is to play previously loaded data, and while playing, 
loading the following data. So there's no delay between the 
transfers.
