There is no known way to detect it, else we'd have used it instead of detecting IBM systems. If you want to bypass the warning and use lm-sensors, *at your own risk*, I can tell you how to do so *in private*. > 3/ I read in the documentation that : > "IBM Thinkpads contain a proprietary Embedded Controller which > is used to access sensors.

Recently, Pam Huntley has been helping us and there now is an official Thinkpad identification chart (http://www.pc.ibm.com/qtechinfo/MIGR-45120.html). Though it will be of some help, it doesn't really solve anything as long as we don't know which Thinkpads (or even other IBM systems, or even other non-IBM systems) have been using the 24RF08. > 5/ is their a SAFE way, to safe that eprom information and make tries > with lm_sensors ?

There are at least two reasons for which it is difficult to do so. First, the EEPROM driver is read-only, so it would require that we implement a writing interface. Second, as fas as I know, you don't know you have destroyed anything before rebooting, and then it's too late. If you can get more information from IBM, please share with us :) Thanks. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
