Currently 4GB AFAIK. The limitations that BeOS had and Haiku had also due to mapping the whole physical RAM into kernel space was removed some years ago (Linux also used to have this limitations years ago). > Are there any 'special fixups' or tricks or special cases for more memory? Our kernel should now support PAE, so it should at least support up to 4GB or RAM, not sure about more. But really, the intended target for Haiku doesn't really need that much yet. François.
