how-to questions

Hello again, while playing with l4 I got couple of (easy) questions. 1. Can DOpE write a log anywhere on filesystem? 2. Where can I see how much memory I can assign to vmlinuz (how much memory uses DOpE and L4)? 3. What are those 4 slide bars by the linux window in DOpE? 4. How can I run more that one Linux process? 5. Can I use pistachio in place of fiasco? If so, how? 6. How do I halt L4 and DOpE? Hope it's not too much to answer. ratko
