Hi again, What about eeproms? Can you load eeprom driver (no lm93) and check if sensors command reports correct RAM module size? Or aletrnatively you can try to use i2cdump (see manpage how to deal with block transfers) to dump it using bytemode and later blockmode. If dumps are OK it means that bus is OK and there is some problem with lm93 or its driver. I hope it helps Regards Rudolf
