Thorsten, I am not aware of a strict 4MB kernel limit - the kernel needs to fit into ST-RAM entirely. ST-RAM may be as large as 14 MB. There is one, but that seems to be related to, at least, page table setup in early kernel space (but my attempts at patching that didn't work either, so

Funny enough I currently got problems with load the kernel on Arrakis, an A3000, although I already reduced the memory from 128M down to 64M with no success. It ran wirh the same setup for months now, until I shut it down for cleaning today. -- Ingo Jürgensmann http://blog.windfluechter.net
