Hello, I am reading some Virtual Machine papers, and found that VMWare has patented certain technology named MultipleWorlds. Anybody please tell me exactly what that MultipleWorlds is about? And is that only technology patentd by them? One more question: VMWare use dynamic binary translator to emulate some "sensitive" instructions. If so, why their softwares are not always compatible with OSes? Is that because their solution is not perfect? (For example I remembered VMWare Workstation didnt support WinXP when WinXP first released. Only after sometime, they upgraded their software to support it) Thank you, AQ ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

But you could get more information in a vmware related forum. ;) Regards, Luciano Rocha ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
