glibc version i586 and i686 conflict

Hi, I'm making a cd with autoyast, using the 'create iso' option. This works fine on the same kind of system (which is a mini-itx board with a via c3 cpu) If I take the cd to other systems, the installation fails because the i686 glibc version is not included on the cd (the i586 version however is on the cd). So I have a couple of questions: - Is it possible to include both glibc versions on the install cd? - Is there a way around this? - What is the logic that determines if the i686 or i586 version is installed? Can this same problem occur for other packages? (I think not, because glibc seems to be the only package in the i686 directory, but I'd like to hear this from an expert too...) Thanks, Sytse
