You do need an exact replica of genuine kickstart file. The most installs require kick40068.A1200 plus those skick files. Some installs even are adapted to A4000, but just some. If your install demands A4000, you probably have a wrong version, as all installs (I think) are made to work with 3.1 A1200 kick file (if requiring a kick file), just a couple with A4000, too. Of course there are also installs requiring A500 kick 1.3.
