Hi, I need some help in explaining how to install 2.10.2 package. The problem I have is that I am compiling kernel on my host computer for a different target board. Installation instructions and make file presented in the package will install necessary files on the host, but not in my source tree which I need to compile for the target . Is there a way to solve the problem? Thanks. -- sasha Juerg Haefliger <juergh at gmail.com> wrote: OK, should have read the whole thread before answering :-) Here's the deal: Starting with kernel 2.6.19, the vt1211 driver is now part of the kernel and there is no need to use Lars Ekman's patch anymore. The new driver is based on Lars' driver but contains some significant changes that render previous sensors.conf files unusable. So if you upgrade to 2.6.19 and use that driver, you also have to have a fairly recent version of the lm-sensors package (I believe 2.10.1 or newer). The lm-sensors package contains a sensors.conf file that has a vt1211 section that is compatible with the new 2.6.19 vt1211 driver. It might need tweaking for your particular motherboard since I only had a M10000 for testing. So I strongly suggest that you upgrade to 2.6.19. I can't provide support for Lars Ekman's patch. ...juerg On 1/19/07, Michelle Dupuis wrote: > > > It looks like your formulas are way off....here are mine (for a VIA PD1000 > mobo).
