r2576 r2733 24 24 Later evolutions were made and the current state is: 25 25 26 1) Sensors-detect accesses VPD information in the BIOS to identify IBM 27 systems. If it finds the VPD structure (which is IBM-proprietary), 28 sensors-detect will print a message and exit. This is a temporary 29 additional measure, which will be removed as soon as the other 30 measures have proven to be efficient. 31 32 2) The probing command (quick write 0) has been replaced by a different 26 1) The probing command (quick write 0) has been replaced by a different 33 27 command (read byte) for addresses where eeproms are known to live. 34 28 This should prevent corruption of 24RF08 eeproms in any system, … … 36 30 no corruption was ever reported using this tool. 37 31 38 3) The i2c-piix4 module (the bus driver that is used for Intel PIIX4-based32 2) The i2c-piix4 module (the bus driver that is used for Intel PIIX4-based 39 33 systems, including IBM Thinkpads) now accesses DMI information 40 34 in the BIOS to identify the system manufacturer. If the system 41 35 manufacturer is IBM, i2c-piix4 will print a message and exit. 42 36 As the 24RF08 is on the PIIX4 SMBus, this prevents access to 43 the 24RF08 , even if sensors-detect was not used.37 the 24RF08. 44 38 45 4) The sequence of probes in the eeprom module (when loaded with39 3) The sequence of probes in the eeprom module (when loaded with 46 40 checksum=1) has been changed so that 24RF08 eeproms will 47 41 not be corrupted. This *should* prevent corruption of 24RF08
