If /proc/cpuinfo shows two CPUS then both of them are working. Some old versions of top supports only one CPU - you need updated top if you want it to see correct CPU info in it. Also some old versions of ps also was broken on SMP boxes. I don't rememeber what exactly was broken. I just remember that old ps shows some stats wrongly on SMP. -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- | Ilya Martynov (http://martynov.org/) | | GnuPG 1024D/323BDEE6 D7F7 561E 4C1D 8A15 8E80 E4AE BE1A 53EB 323B DEE6 | | AGAVA Software Company (http://www.agava.com/) | -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
