Oh nothing specific, I was only unclear of its function as I had an
ITE8705 _and_ an LM90 which seemed superfluous hence my question as to

I can't connect to the lm-sensors.org site, it keeps timing out for the
last few hours. I will attempt at reading the wiki entry later. Should
I start looking for an offset to garner a better reading from the k8

As in my other post to you, it's not exactly accurate, the manufacturer
attempted a fix and broke the rest of the BIOS. I'm guessing with a
compute line to reduce the reading by 10%.
