Sorry, forgot about that! You're right, rm init-code of extenders needs to
know whether it can use existing dpmi or to install it's own dpmi/vcpi
host. Didn't code anything for rm in a long time.

Right, in first case it surely would because no existing dpmi is
available and second case I am unsure, perhaps you mean these real-mode
apps which refuse to work under vm86 at all - I've seen few of them.
Your points are very valid.

Just wanted to say that vm86 detection in rm isn't so useless or harmful.
Btw, I had problems (locks) running emm386 under both vmware and bochs -
though it was year ago, maybe they've improved since then.
