Hi guys
I have a problem with my trusty old Powerbook 3500(Open Firmware  
2.0.1) ....

Whenever I reboot the system it stops with a black screen... but  
forcing it into Open Firmware I just type "boot" and everything boots  
fine....

Somewhere there was a hint with
setenv boot-command " screen" output boot

.. and I tried that but still no luck in getting the system to  
autoboot (yes! the auto-boot? flag is set to true)

Any ideas ??
