At our lab we have a lot of i965-based Intel boxes as well as some
nForce-4 based ones. I use at home also a nForce4-based one and I
realized that none of them equipted qith an AMI BIOS does not show up
temperature zones in ACPI.
I had an ASUS A8N-SLI motherboard with AWARD BIOS where I definitely had
those temperature zones, when I changed the motherboard to an A8M32-SLI,
BIOS came from AMI and the temperature-zones informations via ACPI has
gone. It seemes to me to be an BISO-vendor issue, due to the super IO
chip is of the same brand and only a more modern version in the newer MoBo.
