   (AH) = 80H—SCSI Devices   
   These BIOS services are intended for use by device drivers.   
   Application programs should use operating-system interfaces to   
   access small computer system interface (SCSI) devices.   
      
   The following is a summary of the SCSI functions.   
   (AH) = 00H — Get Device Count (page 2-IN4B-3)   
   (AH) = 01H — Get Device Data (page 2-IN4B-4)   
   (AH) = 02H — Allocate Device (page 2-IN4B-4)   
   (AH) = 03H — Deallocate Device (page 2-IN4B-5)   
   (AH) = 04H — Send Device SCB (page 2-IN4B-5)   
   (AH) = 05H — Send Device Immediate (page 2-IN4B-8)   
   (AH) = O6H — Reset Adapter (page 2-IN4B-8)   
   (AH) = 07H — Set Time-Out Value (page 2-IN4B-9)
