I use at home also a nForce4-based one and I=20 realized that none of them equipted qith an AMI BIOS does not show up=20 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=20 gone. It seemes to me to be an BISO-vendor issue, due to the super IO=20 chip is of the same brand and only a more modern version in the newer MoB= o. Oliver
