Dear Gilles, I have already installed Xenomai, 2.6.0 under Fedora 13 and x86 and 32 bits system and every thing seems OK.
I believe that my questions and your answers has cleared many dark sides of the issue and may be useful for others too on a bet that they can read them some how. Before writing any real time application i needed a deep understanding of the whole logic and a general picture. Sorry to ask questions and take up your valuable time and other people, please forgive me, but what is recorded can be very useful for beginners.
