Call sysctl before sysctl.conf

Hi all,

When openBSD runs my processor at 100%, it makes a noise. Interestingly, when in bios, this noise does not appear.

To get rid of the noise I call sysctl with this:

sysctl hw.perfpolicy=manual
sysctl hw.setperf=99

The problem is, at the beginning of boot, openBSD runs the processor with hw.setperf=100, so the noise is present.

Using a /etc/sysctl.conf with:

hw.perfpolicy=manual
hw.setperf=99

does not help, as this happen too late.

I also tried to use a /etc/rc.securelevel with:
sysctl hw.perfpolicy=manual
sysctl hw.setperf=99

but it also happens too late, and the noise is present (if brief).

Is there a way to make hw.setperf=99 really permanent, or happen even earlier during boot?

Thanks!
Jake
