I've searched my library of DSDT's for fan devices
which are missing _PR0 and found two others that
are broken like this one. (shuttle nforce2, and soyo via)
and both of them are from this BIOS vendor -- Award.
Hmmm, what "Award" should we give this BIOS writer?:-)
This means that the active trip points are worthless
on this machine, as the BIOS is not filling in the hooks
we need to actually control the fan. Presumably the
fan control you've got is entirely SMM /hardware based.
This means also that the former method of over-riding
the active trip-points on this machine had no effect,
other than giving the operator the impression that they were
in control when they were not...
So how high are you able to drive the temperature
with the patch applied and the passive trip point disabled?
