using two different kernels

Hi, I'd like to set up my SuSE 9.0 installation so that I can choose between two different kernels (namely default and smp) at bootup. I am aware that I can do that by adding an entry with the appropriate kernel image in grub (or lilo). My question is: Can I expect everything to work properly after I install the kernels and set up the kernel images in the boot loader? Or do I have to expect to run into trouble because the different kernels need different system configurations? Thanks Klaus __________________________________ Do you Yahoo!?
