The machine (Inspiron 9400) is fast but I saw at certain moments something like "NO-MMX, NO-SSE" (some flags or variables) during the compilation process. I thought then "How come? What a pity not to use these instructions". Can someone tell me what it was and if it is really supposed to be like this? My roots are in Gentoo Linux where it is possible to get the maximum out of a processor when building a system from scratch by using properly certain C and C++ flags. I am pretty sure the same is possible with FreeBSD, however these aforementionned flags raised some questions in my mind... ;) Daniel
