On those few pages I couldn't find if anything had changed with L1 cache for the "Spitfire" but as it was indeed 128 kB for Athlons so far I trust that your figure is right. I don't think it will be able to run in dual processor configuration, that's a pity, I believe Dan said the new Coppermine derived Celerons won't either anymore. Eelco
