Hi on my Elan410 based System it is very easy to change the CPU clock speed by means od two outb commands. I was wondering, if it does some harm to the Kernel if the CPU is reprogrammed using a different CPU clock speed, while the system is up and running. I have a module for the

Hi, I have a brand new Dell Inspiron 8000, laptop. It can run in 700 MHz or 850 MHz. The manual says that the machine/BIOS switches speed dependent on CPU load. I have not installed Linux yet, but it works with Win2000. It is also possible to force the BIOS to one speed if the OS don't like
