 Routine Description:
928 
          This is the interrupt service routine for the Orchid SCSI adapter.
929 
          It reads the interrupt register to determine if the adapter is indeed
930 
          the source of the interrupt and clears the interrupt at the device.
931 
 Arguments:
932 
          HwDeviceExtension - HBA miniport driver's adapter data storage
933 
 Return Value:
934
