Hi Juerg, As almost all Super-I/O chips, the VT1211 can live at two different address pairs, 0x2e/0x2f or 0x4e/0x4f. The vt1211 driver only supports the former at the moment. Some systems use the latter though: http://www.lm-sensors.org/ticket/2149 Could you please add support for the second address? It shouldn't be too difficult, you can simply turn SIO_REG_{CIP,DIP} into global variables and run vt1211_find() twice, once with each possible address pair. The w83627hf, f71805f, pc87360 and pc87427 drivers do it that way already. Thanks, -- Jean Delvare
