Comment 1 Arjan van de Ven 2002-06-21 14:59:30 UTC 
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 15:17:01 UTC 
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 15:24:43 UTC 
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 19:42:37 UTC 
There's some speedstep support in the kernel now...
Comment 5 Kjartan Maraas 2002-08-24 21:52:04 UTC 
Works when I set it to automatic in the BIOS.
