Interestingly, I see only one CPU with e.g. "top", or cat /proc/cpuinfo, etc. I have to tell though that I installed this system by cloning the disk of another PC, which is running a single processor; then booting in the dual processor computer from the cloned disk (with a bootfloppy), and then recompiling the kernel (and rebooting to the new SMP enabled kernel). Seems to me that this is not enough, and I might have missed something. Any advice would be welcome. Thanks Gaspar Jan 15 16:20:47 cfhat2 syslogd 1.4.1: restart.
