LinuxQuestions.org - RealTime Linux with an inappropriate kernel

Hello all,
my problems lay in rtai-linux systems, and i hope that somebody can help me.
I have Linux-Suse 6.4 installed on one PC and worked well with rtai-1.3 kernel, which is adapted to work with linux-kernel-2.2.14.
And on another PC i installed also Suse-10.3, which works properly with rtai-3.3, which is also adapted to work with linux-kernel-2.6.15.
And on each real-time-system i have some written programs that work well.
Now I want to benefit from the worked programs on the first system with rtai-1.3 in the second PC with rtai-3.3.
To do that, i had to make so many changes in Make-file and the other files to work correctly on other rtai version.

Questions :

1- can i in a way install rtai-1.3 on Suse-10.3 "for example".
-- i tried to do that, by installing new kernel-2.2.14 on Suse-10.3 and then i installed rtai-1.3 on it, but it did not work.

2- what the best way to benefit from all written programs on system by the other and with fewer changes.
