Location of yast config files (Slightly OT)

Hi list, can anyone tell me where Yast stores hardware settings? I moved my cdrom from /dev/hdb to /dev/hdc. Unfortunately, yast keeps looking for hdb to install software from. I've manually copied the files I needed and installed them, but in the future it would be nice to know where to look for the config files. I saw a CDrom entry in /var/lib/YaST2/install.inf, but changing that doesn't appear to work. TIA Stefan
