The BIOS on this laptop is unusually sparse, and I don't see any options with regards to the CPU. So, is there something deep inside this machine, either in BIOS or CPU or ??? that throttles the CPU based on load? I have noticed that the fan speed goes up and down depending on what I am doing. I don't see any throttling stuff in `sysctl hw.acpi' like I do on my P2 laptop, so does that mean that CPU throttling is not something that I can control? Also, since the throttling seems to be out of my hands, is it possible that the CPU is actually running at 2.2GHz when it needs to, depending on load? I know that amd64 is a growth area, and I don't expect it to be as rich as i386 is... yet. I am not a programmer, but I follow directions pretty well and am willing to help further FreeBSD's amd64 support in any way that I can. --=20 Michael W.
