I don't know if there's a minimum requirement. If so it at least appears 
to be not documented or this only happens on QEMU.

I'm using the stripped version which is 734040 bytes and it did not work 
with 128MB as I described but I think this is not related to openbios 
settings but to how MorphOS decides its memory layout. I hope someone can 
confirm this and explain why is it happening. Until then using at least 
256MB memory is a good enough workaround for me.

I'm currently stuck at the place I've described yesterday which is very 
near the end of the initialisation of the Quark kernel but I don't know 
why is it failing. I hope to get some help with this because it is rather 
difficult to tell without source and knowledge about how Quark works.
