No, the device isn't even listed on lm-sensors.org's wiki, I am not aware of anyone working on it. The datasheet isn't available for download from Nuvoton, but can probably be requested from them. > Then again, I wonder if it might be better to come up with an SSDT I can > dynamically load to define the ACPI FAN and TZ objects and let the > regular acpi driver manage it. What an horrid idea. The ACPI FAN and TZ interfaces are very limited. If the ACPI BIOS doesn't block access to the NCT6776F's I/O ports, you'll be much better with a native driver. OTOH I admit I am surprised to see Asus move away from the ATK0110. -- Jean Delvare
