If your BIOS In case of P-M (Banias), speedstep does work differently, and this will not work. Be sure to disable speedstep stuff in such case (or implement it). SpeedStep also work if ICH-2M, and it is easy to add it in your patch (but probably not the deeper sleep stuff though, especially if you have an older PIII, but sleep should be ok). -- Ducrot Bruno -- Which is worse: ignorance or apathy? -- Don't know.
