I found that a heap size of 500k works for me (so I made it 512k just in case).
I still crash the first time I boot. After a few tries I found that if I let
the system come up and complain about not finding fs and then restart with
the mouse held down, change heap to 512k (turn off ram disk if you wish)
then hit OK the system comes up. You still have to go to File->Configuration
and change the heap again or it will not be there next time you start.

hope this helps.
