 * $Log:   V:/Flite/archives/TrueFFS5/Src/FLIOCTL.C_V  $
 * 
 *    Rev 1.11   Jan 29 2002 20:08:44   oris
 * Changed LOW_LEVEL compilation flag with FL_LOW_LEVEL to prevent definition clashes.
 * 
 *    Rev 1.10   Jan 28 2002 21:25:08   oris
 * Removed error massage from FL_IOCTL_SET_ENVIRONMENT_VARIABLE now simply returns flBadParameter.
 * Replaced FL_IOCTL_WRITE_IPL (now return flBadParameter) with FL_IOCTL_EXTENDED_WRITE_IPL in order to support Strong arm mode and download flags.
 * Changed FL_IOCTL_SET_ACCESS_ROUTINE interface to support update of all DiskOnChip memory access in a single call.
 * Added FL_IOCTL_GET_ACCESS_ROUTINE to get current DiskOnChip memory access routine pointers.
 * 
 *    Rev 1.9   Jan 23 2002 23:31:44   oris
 * Added support for 2 additional parameters to FL_IOCTL_VERIFY_VOLUME call.
 * 
 *    Rev 1.8   Jan 17 2002 23:01:48   oris
 * Removed warnings.
 * Forced FL_IOCTL_SET_ENVIRONMENT_VARIABLES to return  flFeatureNotSupported in order to force the use of the new routine.
 * Added 3 new ioctls
 *  - FL_IOCTL_EXTENDED_ENVIRONMENT_VARIABLES - Set environment variables
 *  - FL_IOCTL_SET_ACCESS_ROUTINE -set access routines
 *  - FL_IOCTL_VERIFY_VOLUME - check volume for errors caused by power  failures.
 * 
 *    Rev 1.7   May 09 2001 00:45:48   oris
 * Changed protection ioctl interface to prevent the use of input buffer as an output buffer.
 * 
 *    Rev 1.6   Apr 16 2001 13:43:28   oris
 * Removed warrnings.
 * 
 *    Rev 1.5   Apr 09 2001 15:09:20   oris
 * End with an empty line.
 * 
 *    Rev 1.4   Apr 01 2001 15:16:26   oris
 * Updated inquire capability ioctl - diffrent input and output records.
 *
 *    Rev 1.3   Apr 01 2001 07:58:30   oris
 * copywrite notice.
 * FL_IOCTL_FORMAT_PHYSICAL_DRIVE ioctl is not under the LOW_LEVEL compilation flag.
 * Bug fix - BDK_GET_INFO no longer calls bdkCreate().
 *
 *    Rev 1.2   Feb 14 2001 02:15:00   oris
 * Updated inquire capabilities ioctl.
 *
 *    Rev 1.1   Feb 13 2001 01:52:20   oris
 * Added the following new IO Controls:
 *   FL_IOCTL_FORMAT_VOLUME2,
 *   FL_IOCTL_FORMAT_PARTITION,
 *   FL_IOCTL_BDTL_HW_PROTECTION,
 *   FL_IOCTL_BINARY_HW_PROTECTION,
 *   FL_IOCTL_OTP,
 *   FL_IOCTL_CUSTOMER_ID,
 *   FL_IOCTL_UNIQUE_ID,
 *   FL_IOCTL_NUMBER_OF_PARTITIONS,
 *   FL_IOCTL_SUPPORTED_FEATURES,
 *   FL_IOCTL_SET_ENVIRONMENT_VARIABLES,
 *   FL_IOCTL_PLACE_EXB_BY_BUFFER,
 *   FL_IOCTL_WRITE_IPL,
 *   FL_IOCTL_DEEP_POWER_DOWN_MODE, 
 * and BDK_GET_INFO type in FL_IOCTL_BDK_OPERATION
 * Those IOCTL were not qualed and the TrueFFS 5.0 should be release with revision 1.0 of this this file.
 *
 *    Rev 1.0   Feb 04 2001 11:37:36   oris
 * Initial revision.
