Comment 1 Arjan van de Ven 2002-06-21 10:59:30 EDT

Is this a laptop that you booted with power disconnected ?
If so, then yes it was really running at 800 Mhz when this value was determined

Comment 2 Kjartan Maraas 2002-06-21 11:17:01 EDT

No. It was running on AC while I booted. I just rechecked now and it's really
true :)

Comment 3 Kjartan Maraas 2002-06-21 11:24:43 EDT

So I checked in the BIOS and after setting the Speedstep config from "Disabled"
to "Automatic" it's now seen as a 1200 Mhz processor. What's up? And did it
really just run at 800 before?

Comment 4 Michael K. Johnson 2002-06-25 15:42:37 EDT

There's some speedstep support in the kernel now...

Comment 5 Kjartan Maraas 2002-08-24 17:52:04 EDT

Works when I set it to automatic in the BIOS.
