When installing SLES 10 SP4, what file(s) install the kernel and modules onto the system? I have tried injecting drivers into the initrd file on a boot ISO that I am using to do an AutoYaST deployment and the drivers work when booting off the ISO, but when SLES installs, the drivers are not working when it boots off the hard drive.

Maybe I need to inject the drivers into the initrd file under boot/x86_64/loader on the Install media? Or is there another file that contains all the modules and kernel?
