// 6 1/03/13 10:51a Vyacheslava
// Added modification to check for LOAD_OPTION_HIDDEN and ignore hidden
// boot options in creating "DefaultBootOrder" variable.

// 5 10/15/12 10:31a Vyacheslava
// [TAG] EIP103603
// [Category] Bug Fix
// [Severity] Critical
// [Symptom] DefaultLegacyDevOrder is corrupted
// [RootCause] SetDefaultTseBootOrder () corrupts the data which is not
// the Boot Order.
// [Solution] for( i = 0; i < (Order->Length / (sizeof (UINT16)) - 1);
// i++ )
