Yast can't find CD

YAST needs help finding my cd-rom drive. Originally my cd-rom drive was at "hdc" (master on secondary IDE). I recently installed an additional hard drive as master on the secondary IDE (hdc) and moved the cd-rom drive to slave (hdd). Now, when I install software using YAST I get an error that it can't access the cd-rom. When I display the error details it indicates that YAST is looking at "hdc" for the cd-rom. The error-details dialog allows me to enter "hdd" and it then allows me to proceed with the install. How do I inform YAST that my cd-rom is now at "hdd". By the way, my desktop CD-ROM link works fine. Thanks, Matt
