The HW should make sure that LSB is LSB and MSB is MSB. Also those HW drivers won't turn anything around. Endiannes problems usually appear when several machines using different endianness meet (like when you share files). The only way endiannes may hurt you is when a program depends on it (like when the program rips a long integer to bytes and expects the LSB on the lowest address). So you have to search for those ugly casts and unions used to do that. Ole -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln! Fotogalerie online mit GMX ohne eigene Homepage!
