I had the same problem. Make sure that you are using the latest
version of mol. I believe that the minimum ROM necessary is OS 8.6
or 9. I had success with 9. You may also want to try a newer
kernel, although 2.2.14 should be fine. I'm using the one that came
with LinuxPPC 2000 (LinuxPPC Standard 2.2.15pre3).
