-  by the IDE controller driver based on the response to the Identify Drive command.
-

-
-  For Serial ATA (SATA) controllers, this member function can be used to disqualify

-  Returns the information about the optimum modes for the specified IDE device.
-
-  This function is used by the driver entity to obtain the optimum ATA modes for
-  a specific device.  The IDE controller driver takes into account the following
-  while calculating the mode:
-    - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
-    - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()
-
-  The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
-  for all the devices that belong to an enumeration group before calling
-  EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.
-
-  The IDE controller driver will use controller- and possibly platform-specific
-  algorithms to arrive at SupportedModes.  The IDE controller may base its
-  decision on user preferences and other considerations as well. This function
-  may be called multiple times because the driver entity may renegotiate the mode
-  with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().
-
-  The driver entity may collect timing information for various devices in any
-  order. The driver entity is responsible for making sure that all the dependencies
-  are satisfied. For example, the SupportedModes information for device A that
-  was previously returned may become stale after a call to
-  EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
-
-  The buffer SupportedModes is allocated by the callee because the caller does
-  not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
-  is defined in a way that allows for future extensibility and can be of variable
-  length. This memory pool should be deallocated by the caller when it is no
-  longer necessary.
-
-  The IDE controller driver for a Serial ATA (SATA) controller can use this
-  member function to force a lower speed (first-generation [Gen1] speeds on a
-  second-generation [Gen2]-capable hardware).  The IDE controller driver can
-  also allow the driver entity to stay with the speed that has been negotiated

-  Disqualifies specific modes for an IDE device.

-  to recalculate modes. This function allows the driver entity and the IDE
-  controller driver to negotiate the timings on a per-device basis. This function
-  is useful in the case of drives that lie about their capabilities. An example
-  is when the IDE device fails to accept the timing modes that are calculated
-  by the IDE controller driver based on the response to the Identify Drive command.
-
-  If the driver entity does not want to limit the ATA timing modes and leave that
-  decision to the IDE controller driver, it can either not call this function for
-  the given device or call this function and set the Valid flag to FALSE for all

-
-  For Serial ATA (SATA) controllers, this member function can be used to disqualify
