Yeah, I was wondering if it might be something in the BIOS settings.
I'll google around and see what I find. I don't know if the first
panic was a bad pte error since the machine was running headless.

I kinda wondered if heat might be an issue, since it was kind of
tucked away in a spot with bad airflow. I'll try the memtest thing.
Is there a way to get the CPU temp in FreeBSD?
Meh. let's see if this thing'll actually compile...
