The discs are actually generated by a Dell service called imagedirect. The first disc contains a 1.44MB boot image, it has a bin folder which contains some basic dos utilities and the ghost.exe, and an image folder that contains the ghost image which is broken into 650MB segments. The second dvd contains the image folder with the rest of the files. Using Imgburn, I imported the boot sector from the first dvd, then added the bin folder and the image folders from both DVDs, but the resulting DVD did not boot.
