I did this and let it ponder for a long while. I then compared the times given for the primary variants with those on my P166 (128 MB RAM, 100 MB hash tables). I noticed that my P133 Toshiba notebook stayed constantly at about 72% the speed of my P166 desktop machine (GA 586DX dual Pentium board, 512 KB sync. cache, 512 MB cacheable area). This proves beyond doubt that the Toshiba Tecra caches >64MB RAM. Moritz
