USING SOFTMPU: DREAMBLASTER S2P MODE

Run SoftMPU specifying the parallel interface to be used and the base port
address of the MPU-401 interface, e.g.

  SOFTMPU.EXE /MPU:330 /OUTPUT:LPT1
  
To enable MT-32 compatibility, add the /MT32 switch to the command line, e.g.

  SOFTMPU.EXE /MPU:330 /OUTPUT:LPT1 /MT32

A Sound Blaster base port address and IRQ can optionally be specified if
MPU-401 interrupts are required.
