This value should be used only if the HBA can queue multiple requests and support auto-request sense or tagged queuing.

All miniport drivers must have a HwScsiStartIo routine. The miniport driver should complete all pending requests and must reset the given bus. In this callback, the miniport driver reenables interrupts on the HBA. Need your help I am very new to windows device driver.
