Sorry, but I don't remember the site, however you can try to
http://www.dragoncity.ne.jp/~sokonuke/bootcd.html or
http://www.dreamadictos.com/utilidades/bootcd.html. If the image file is for nero you will burn it with nero without do other.
If image file is *.cdi you will use cd2nero for converting it, is very simple to do, and then you can use nero to burn it.
I have an analogic dial-up otherwise I send you my files.
Bye
