Thank you for your info, Art! But it is a kind of bad luck for my interest. You say your Vista reports 4GB installed. It is an ambiguity because there is a well known fact that Win32 can't use more than 3.2 GB. But! Maybe your Vista can see that odd 0.8 GB exactly due to integrated video "help"? I mean Vista shows us hybrid value of memory amount: amount of RAM used directly by Windows + amount of RAM reported by integrated video.
