SLES 9 install source for i386 and x86_64

Hi Is it possible to setup a combined install repository for i386 and x86_64? I also want to include SP2. I know how to do that for i386 alone. How do I do it for both? What made me ask is the difference in the file content and media.1/product on the first CDs. TIA, Andreas -- Andreas Vetter Universitaet Wuerzburg
