Yager Pc Dvd Rom

[Photoshop kid]

Hi all,
Just bought Yager, would like to back up but do not have a dvd writer at the moment.

I know it`s possible to put on cdr`s, I have made an image in Alcohol 120%, which split it into 700mb chunks, should i just make one large image?

How do i then write this to cdr, the total size is only about 3.8gb, so i wont need loads of cd`s.

Am i right in thinking the data needs to be written in such a way that when the prog is installing it ask for certain cd`s to be inserted, cd 1 cd 2 etc how do i do that?

Any help please
