Years?, I'm not so sure. When I downloaded the MMX specifications 3 months ago one of my friend said: "Intel will implement that in more than 1 year, not in months ..." was too wrong. Actually the base platform is moving to the Intel architecture and in some month you'll get only Pentium motherboards. The main purpose of the MMX is to write device drivers so I guess that you'll see that the manufaturers (of hardwar and softwar) will ship drivers for 386 and for MMX. Think about it, MMX will speed up things like video-conference a lot, so an enterprise supporting MMX will have a better product, for example with your software you'll be able to have more people talking in the video-conference using the same CPU power. There are a lot of things that will be benefited from it and one of the things could be the DirectX drivers ... SET --------------- 0 -------------------------------- Salvador Eduardo Tropea (SET).
