Hi, Thanks, Jean, for the info about the "IBM Laptop detected" problem. The i2c-piix4 bus driver now loads with no problem on this IBM eServer 335. However, sensors-detect still isn't finding any sensor chips on this system. Is there a giant table somewhere that lists motherboard/chip combinations so I can find the appropriate drivers for this system? Or any general guidelines to what IBM or Serverworks prefer to use with their systems/electronics? Could the sensor chips be proprietary? Or has anyone used sensors on these machines and knows offhand? :) Are there any gotchas with regards to installing the latest i2c/lmsensors (2.9.0) on an older kernel (2.4.21)? I know this machine has two Xeon processors, and Xeons have embedded temperature sensors, but have not had much luck trying to access them after inserting the xeontemp lmsensors module - just wondering if my old kernel could have anything to do with it. Any insight is appreciated! Thanks, - Armen
