We do not know which kernel version, which xenomai version, which adeos
I-pipe version.

So, you have a core i7, anything newer than "pentium pro" (an older than
ten years old architecture) should do, but better select the processor
you actually have or the nearest substitute: so, assuming you are
compiling a 2.6.38 kernel, "core 2/newer xeon" should do. Also note that
a core i7 is able to run in 64 bits mode, so running it in 32 bits mode
is a bit a pity.
