I entered the following into the /boot/loader.conf file: hint.acpi.0.disabled="0" Still no luck though, the default option on the loader menu boots without ACPI. When hitting the second option you see ACPI being enabled i.e. /boot/kernel/acpi.ko being loaded. This doesn't happen with option 1 even with the above in my loader.conf file. :-/ Somebody else on this list mentioned the i440BX chipset being a bit flakey with ACPI which is why it might not be enabled by default, but with ACPI it seems to work nice enough for everyday use, fans go on and off, system shuts down nicely etc. The only reference to my chipset I can find on the blacklist is this: INTEL - 440BX (Seattle 2) - 0x00001000 (old) <= Field beyond end of region It's listed as non-critical.
