  Title:       Get Disk System Status
 
  Description:                                          [PC] [AT] [PS/2]
 
     Returns the status of the most recent disk operation. On fixed
     disks, error code 11h (ECC data error) indicates that a
     recoverable error was detected during a preceding Read Sector (Int
     13h Function 02h) function.
