Motherboard: ASUS P4C800-E Deluxe
Harddisk:    Samsung SP2514N connected to Onboard Promise PDC20378 Controller
             RAID Ultra ATA 133 connector.
             In BIOS-Setup it's configured to SATA mode (SATA or PATA or       SATA+PATA is possible, but only in SATA mode, it'working with Suse 9.3)

This harddisk was recognized as /dev/sdc under Suse 9.3 and was working fine.
