Seems to work fine, this time ;-) dmesg: i2c /dev entries driver i2c_adapter i2c-0: nForce2 SMBus adapter at 0x5000 i2c_adapter i2c-1: nForce2 SMBus adapter at 0x5100 i2cdetect -l: i2c-1 unknown SMBus nForce2 adapter at 5100 Algorithm unavailable i2c-0 unknown SMBus nForce2 adapter at 5000 Algorithm unavailable But..., a stupid question : what can I do with this i2c busses ? What is used for, knowing that it87 provides temp, fan, volt etc. What does "Algorithm unavailable" mean? Which one must I use (PCF ? PCA ?) Thanks, anyway. -- Fred.
