Hello, thanks all for your answers. This is different hardware. Unfortuantely that box went in production, but I'll see if I can fix another maschine, I have the S3200 Server board in spare. > I think that I got some additional evidence that SMI handler just clears timeout > status bit and doesn't do anything else. > > 1.
