Just try "isaset -y -f 0x4b9 0x08". That should do the trick Asus recommends. If you confirm that the W83792D then appears on the SMBus (as probed by sensors-detect or i2cdetect) then we'll have to integrate the trick. For 2.6 there is a place dedicated to this (pci/quirks.c). For 2.4 there is none so we'll just document the fact that isaset must be run prior to loading the smbus driver, or integrate the operation into the smbus driver itself (shouldn't be too hard). I still wonder what device is at 0x4b9. According to the snapshot of /proc/ioports you sent, your linux system doesn't know about it. Thanks, -- Jean Delvare
