SLES9-SP3: SATA-driver not installed?

Hi everyone, I have successfully installed SLES9 SP2 via autoyast and are now switching to SLES9 SP3 install-source. Install goes fine, but after reboot I get: Waiting for device /dev/sda5 to appear: .....not found -- device nodes: No root device found: exiting to bin/sh It a machine with SATA-controller, and it seems like SATA-support is missing from the installed kernel? I read in the docs that the system with drivers has changed, now a custom initrd is built during install. Seems like it cannot identify the correct driver for the SATA-card and does add that to the initrd. How do I add this driver myself during install? ( Or, is this really another problem? ) Regards Daniel
