Dear Sir,
It works !

. I have got to do it also in mozilla's applications. Didn't think it were also necessary to reach suse server.
Better ask befor make mistake ...
Witing about mistakes, after meeting this ex-problem, I tryed to "repair" the application with the DCD i wrote and used to install.
Making this the boot section has been modified and I have no acces to boot winxp anymore.
As I am in a "trial" phase to run suse forever, I still need to run my old xp.
Is it a way to change the boot selection to be able again to run winxp ?
Many thanks in advance
