All PC OSs start out in real mode after a reset/reboot, and switch over to 
protected mode, so Xen's real mode implementation can't be all that bad. It 
sounds like this is a problem with OpenSolaris, not Windows. The real test 
would be running Win98 command.com - the classic example of real mode 
switching. Anyone have trouble with that?
