Has any progress been made in getting a module selected for the VIA C7 processors? I had attempted to use Juerg's c7temp, however, due to HP's thermal monitoring BIOS settings, I did not get data. I would be interesting in testing Harald's module, if it has been selected. Could someone help direct me in this? -- Justin Chudgar Information Technology Consultant 5040 Saddlehorn Rd, Weed, CA 96084 530-938-9692 (Home Office) On Friday 10 July 2009 03:00:02 am lm-sensors-request at lm-sensors.org wrote: > Send lm-sensors mailing list submissions to > lm-sensors at lm-sensors.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.lm-sensors.org/mailman/listinfo/lm-sensors > or, via email, send a message with subject or body 'help' to > lm-sensors-request at lm-sensors.org > > You can reach the person managing the list at > lm-sensors-owner at lm-sensors.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of lm-sensors digest..." > > > Today's Topics: > > 1.
