No, it should work equally well. Causes could be: 1* You forgot to unload w83781d before loading w83627hf. 2* Your chip is actually using i2c-nforce2, not i2c-isa. 3* You chip is not a W83627HF and is not supported by the w83627hf driver. 4* Both drivers use different detection mechanisms. The w83627hf driver relies on Super-I/O configuration, while the w83781d driver tries an arbitrary ISA address. Jean
