Hi all! I've just upgraded to vanilla 2.6.23. The problem is that voltages have to be specified in VID (volt id) and not in mV. I use the phc 0.3.0 patchset. Did anyone manage to get undervolting to work? How can the vid-s be calculated? Thanks, Csaba -- Macskasi Csaba bitumen at tuxworld dot homelinux dot org http://tuxworld.homelinux.org:81/
