The reported SpeedSteps are not related to acpi. You do not need acpi to throtle the cpu. Just use "sysctl hw.setperf" apmd(8) has the ability to adjust hw.setperf dynamically (regardless of whether you have apm or not). I prefer the "cool running" mode which keeps the speed at the lowest unless it is needed by some cpu intensive operation. Check the manual page for details. Setting apmd_flags="-C" in /etc/rc.conf.local is the way to start it at every boot. -- In theory, there is no difference between theory and practice. But, in practice, there is. _______________________________________________ Openbsd-newbies mailing list [email protected] http://mailman.theapt.org/listinfo/openbsd-newbies
