Program: SBOS is a SoundBlaster emulator for the Gravis UltraSound
Range: SBOS may use INT 78-INT 7F

Notes: the installation check for SBOS is to test for the ASCII signature
     "SBOS" at offset 0Ah in the interrupt handler's segment (similar
     to one of the possible EMS installation checks)
   this function may not be called if any SBOS vectors have been hooked
