You see, I did not read the data sheet more carefully than you after all ;) Seen from that point of view, it could clearly have been connected to the I2C bus. Still we did not see it, so it is either hiding, or elsewhere. Maybe you could get some info from Chrontel and/or Intel? -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
