     74We would very much like to support IBM systems which contain 
     75non-proprietary sensor devices. Unfortunately, until we have 
     76a reliable identification method implemented, we must 
     77blacklist all IBM systems to minimize the chance of eeprom corruption.

    7479We do not have any reports of 24RF08 eeproms on non-IBM systems.
