On re-reading your first post, it is not clear that you really understand what boot floppies really do. If you can boot knoppix without boot floppies then you do not need them and making them will not help you at all. They are only used on older computers that would not boot a CD properly. The above advice on useing DSL is still good, or the toram option if you have enough memory to hold the entire Knoppix image.
