  \r
  For most of today's controllers, MaxDevices will either be 1 or 2. For SATA \r
  controllers, this value will always be 1. SATA configurations can contain SATA \r
  port multipliers. SATA port multipliers behave like SATA bridges and can support\r
  up to 16 devices on the other side. If a SATA port out of the IDE controller \r
  is connected to a port multiplier, MaxDevices will be set to the number of SATA \r
  devices that the port multiplier supports. Because today's port multipliers \r
  support up to fifteen SATA devices, this number can be as large as fifteen. The IDE  \r
  bus driver is required to scan for the presence of port multipliers behind an SATA \r
  controller and enumerate up to MaxDevices number of devices behind the port \r
  multiplier.    \r
  \r

  This function is used by the driver entity to pass detailed information about \r

  is the pointer to the response data buffer. The IdentifyData buffer is owned \r

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

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

  Returns the information about the optimum modes for the specified IDE device.\r
\r
  This function is used by the driver entity to obtain the optimum ATA modes for\r
  a specific device.  The IDE controller driver takes into account the following \r
  while calculating the mode:\r
    - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()\r
    - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()\r
\r
  The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData() \r
  for all the devices that belong to an enumeration group before calling \r
  EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.  \r
  \r
  The IDE controller driver will use controller- and possibly platform-specific \r
  algorithms to arrive at SupportedModes.  The IDE controller may base its \r
  decision on user preferences and other considerations as well. This function \r
  may be called multiple times because the driver entity may renegotiate the mode \r
  with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().\r
    \r
  The driver entity may collect timing information for various devices in any \r
  order. The driver entity is responsible for making sure that all the dependencies\r
  are satisfied. For example, the SupportedModes information for device A that \r
  was previously returned may become stale after a call to \r
  EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.\r

  not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE \r
  is defined in a way that allows for future extensibility and can be of variable \r
  length. This memory pool should be deallocated by the caller when it is no \r
  longer necessary.  \r

  The IDE controller driver for a Serial ATA (SATA) controller can use this \r
  member function to force a lower speed (first-generation [Gen1] speeds on a \r
