Problem installing Aurora linux for Sparc 1.0

Hi Folks,
            I downloaded the iso images and burned them on CD at 8x. I 
am trying to load this on a ultra 5. The system tries to boot off the CD 
and gets stuck giving a "S" for some time, I assume the Silo is to 
follow. Then after about 20 seconds it says "Program Terminated". I have 
tried to burn with different CD 's, I use nero to do the burning. Could 
someone point out what I am doing wrong, I suspect it is with the CD not 
sure what it is. I an able to look through the CD on a windows system 
and it shows me the full directory structure.


Thanks.
Jag.
