As of FreeBSD 6.2 RELEASE, SMP systems are correctly detected and the SMP kernel is used, no need to rebuild kernel. I have such an old hardware arround (Dual P3@500) and 6.2 RELEASE loaded the SMP kernel as expected. Same thing on shiny new Core2Duo machines. Try a reinstall, if this a testing machine and you'll notice that the SMP kernel is loaded by default, unless some other strange hardware problem exists. -- RTFM and STFW before anything bad happens _________________________________________ Thanos Rizoulis Electronic Computing Systems Engineer Larissa, Greece FreeBSD/PCBSD user
