SLES 9 SP2

Hello, I have a question in regards to the auto install procedure. Using YAST, I set up a NFS share where I have loaded the 6 CD for SLES9 (64 bits) and then the three SP2 CD's. When I installed a server via NFS, I got the message, "Insert SUSE SLES 9 Service Pack 2 CD 1" right before SUSE is ready to install. I have another NFS server for 32 bit distro and I did not experience this problem. Any suggestion? Thank you very much for your help Kurt
