Since I installed Windows Vista, I've been looking for at way to get my Asus A8N32 motherboard to support Cool'n'Quiet. No drivers or bios upgrades were available on the slow Asus website. I bumped into a post telling about an unofficial 1403 bios, that supposedly supports CnQ under Vista 32/64. I took the chance and installed the bios and it seems to work fine. The bios (crc32: 9796387A) can be downloaded from here or here. Update: Asus released a 1405 beta.
