This chip is how you may be able to access sensor chips, it is not a sensor chip itself. > Back when this was a Windows machine, I ran Everest Home, and it was > able to read everything, and claimed LM81 and MAX1617A chips for > whatever its worth... Good news is that both are supported under Linux, so if that's really what your system has, there is hope. > Googling found exactly one reference claiming this was possible on a > linux machine: > http://lists.us.dell.com/pipermail/linux-poweredge/2005-July/021985.html This is a pretty old post, not sure everything said there still applies. > > I tried with no luck: > modprobe -r i2c-piix4 > modprobe i2c-piix4 The post said to pass force=1, but you did not. > I'm not sure if its related, but "i2cdetect -l" returns nothing. Do you have i2c-dev loaded? i2cdetect won't work without it. If you do and "i2cdetect -l" still doesn't list the SMBus, please check the kernel log when you try to (re)load i2c-piix4. > Below is part of the output of "lspci -nn -vv" > 00:0f.0 Host bridge [0600]: Broadcom CSB6 South Bridge [1166:0203] (rev a0) > Subsystem: Broadcom Device [1166:0201] > Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- > ParErr+ Stepping- SERR+ FastB2B- DisINTx- > Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium > >TAbort- <TAbort- <MAbort+ >SERR- <PERR- INTx- > Latency: 32 > Kernel modules: i2c-piix4, sworks-agp Two drivers for the same device, looks wrong. You should try getting rid of (via blacklisting) sworks-agp and see if it helps any. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
