For a headless system, create the file /boot.config and add the following characters to it: -Dh Then, in /etc/ttys, edit the line(s) for your appropriate serial consoles. Mine looks like this: ttyd0 "/usr/libexec/getty std.9600" vt100 on secure > 7) does FreeBSD support 2 CPUs on i386? > Yes, it does.

If I were you, I would use 4.10. Keep in mind, though, that the upgrade process from 4.x to 5.x is a complete reinstall, for the most part. I guess there are some people that have been able to do it, but never I or anyone I know here. I've used 5.2.1 on my home machines, but they're just a little too buggy for my liking. ACPI can cause problems, and seems to be the biggest source of bugs. On the other hand, if you need power management, I've never been able to get APM working in 4.x. I hope this helps to answer some of those questions. Eric F Crist
