Norton ghost 11.5 bootable not working in IBM server

I have Norton ghost 11.5 bootable CD. I am not able to boot Norton ghost 11.5 CD in my IBM x3630 M4 server. But windows server CD boots properly. But other desktop PCs and my old server working properly with that CD. What is the problem? I have checked by changing media,rewriting the CD etc. When i log a call to IBM, they are telling that you may face this type of problems only when that boot media is not supported by the server. Whether it is correct? Why IBM server only not supporting norton ghost?
