The system worked great. I decided to move to using dual processors, so I acquired 2 PIII 667 cpus. (According to Intel's site, they state it should work in a dual CPU setup). Now in my mind, Im thinking the process of moving from a single setup to a dual setup is -> 1. Make sure the system runs with one processor. 2. Install second processor. 3. Rebuild kernel for SMP operation For some reason, when I install the second processor, and boot the box, it hangs at random places during the boot process of FBSD. If I boot the box (with the 2 cpus installed), and go to the bios screen, it will sit there, and not hang. If I run FBSD with either one of the PIII 667s it will work great. So my question. Is there a particular sequence of events that must happen when going to a dual CPU setup?? If not, has anyone have any problems with the motherboard that Im using?? Currently using: 4.9-RELEASE-p1 Thanks for your advise..
