USING GHOST 10.0

Here is my issue, I’m using Ghost 10.0 to create an image of my computer. The image will be two DVD’s, I have made several images using sysprep and ghost before but with only one DVD. Now the image must be on two, how to I burn/create pointers in the image so that is will point to the second DVD? Also I was using a boot 98 file to make my image bootable, but if I boot to ghost is makes a .GHO file, which I have a boot file I can add right to my DVD, but if I make the image in the windows screen it makes a .v2i file, what is that?
