Hi Mehran, I think it has also W83792D on it. This chip is supported in 2.4 and for 2.6 some patches exists too. (not yet in mainline) I belive you will need latest beta bios for k8n K8N 1007.009 K8N Beta BIOS 1007.009 http://support.asus.com/download/download_item.aspx?product=1&model=K8N&SLanguage=en-us Then you will be able to "see" this chip on Linux. If you have 2.4.x kernels go ahead with lm_sensors 2.9.1 If you have 2.6.x kernels you can try this http://lists.lm-sensors.org/pipermail/lm-sensors/attachments/20050621/8dfe2e28/patch_w83792d-2.6.12-0001.gz And this http://lists.lm-sensors.org/pipermail/lm-sensors/attachments/20050706/3a674472/w83792d-driver-QUIET-2.6.x.patch-0001.gz You will need lm_sensors CVS userspace utillites for this (make user; make user_install;) Regards Rudolf
