Oh, of course. That was implied. The OS has to run in protected mode, not real
mode, to take advantage of this. But my point is that any OS that claims to have
any form of memory protection on x86 processors, must use the hardware
protection of the processor. It cannot be made in software. And as such, all
OS'es are equally good. At any rate, my practical experience is that Windows
2000 is as stable as Linux regarding this.
