Hi List I do sensors-detect and get: System vendor: System Manufacturer We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no): Probing for PCI bus adapters... Use driver `i2c-piix4' for device 00:04.3: Intel 82371AB PIIX4 ACPI Use driver `i2c-voodoo3' for device 01:00.0: 3Dfx Voodoo3 Probe succesfully concluded. Then I continue with YES and get: We will now try to load each adapter module in turn. Load `i2c-piix4' (say NO if built into your kernel)?

Any idea what this onresolved symbol is doing? Thanks for any help and hints. Zeno
