Hi Forest, Well the bottom line is that the value returned in the EAX register (0xC000002) is zero for all of these cases where people report 0 C CPU temp. I haven't had the time yet to figure out what is different about these CPUs and why they don't seem to adhere to the spec that I have. One possibility is that my spec is old and things changed in the meantime and another one is that the BIOS disables the thermal diodes in the CPU. I have some sample BIOS code from VIA which does that but I haven't had the time yet to figure out if that applies in this case. ...juerg On Sat, Sep 27, 2008 at 1:57 PM, Forest Bond <forest at alittletooquiet.net> wrote: > Hi Juerg, > > On Sun, Sep 07, 2008 at 11:32:17AM -0700, Juerg Haefliger wrote: >> On Fri, Sep 5, 2008 at 11:45 AM, Forest Bond <forest at alittletooquiet.net> wrote: >>> On Thu, Jul 10, 2008 at 08:08:16AM +0200, Wilken Gottwalt wrote: >>>> Am Montag 07 Juli 2008 19:29:00 schrieb Juerg Haefliger: >>>>>> Am Montag 07 Juli 2008 08:11:02 schrieb Juerg Haefliger: >>>>>>>> It's the Artigo-Box from Via with a PX10000 board >>>>>>>> (http://www.via.com.tw/en/products/embedded/artigo/). >>>>>>>> No, there are no bios settings dealing with thermal or power >>>>>>>> management.
