Hi all: I searched the last 6 months of this list and found no reference to SMSC's EMC6W201 hardware monitoring and fan control device for multi-processor systems. I presume that means that it has not been considered yet as one of the new devices to be supported. I would like to add it to the short list and will provide a little info to get things rolling. Please make any reply to me directly as I am unable to monitor this list at this time. If need be for testing, I'll make arrangements to change that. It is a relatively new device(July 2005) from SMSC and is being used on, at least, the Gigabyte(GBT) Dual Opteron 2CEWH mainboard -a single EMC6W201 on SMBus 2.0. I am not sure how many others use it now or intend to in the future. The 2CEWH mobo also uses the ITE IT8712F Super I/O device but, according to GBT, it only functions as the I/O controller. The hardware monitor & control functions are handled by the EMC6W201 device. Perhaps needless to say, that confused lm_sensors a bit. I was unaware of the additional chipset when I performed the lm_sensors setup so I made some mistakes too. Of course, the result is pretty wacky output from some readings and not all monitors are available. I checked the lm_sensors website and found that the SMSC EMC6W201 is not listed with even partial support. I also see that SMSC is not listed as one of the "supporters" for lm_sensors. I certainly hope that only means they have not been asked. The EMC6W201 product page is located here: http://www.smsc.com/main/catalog/emc6w201.html#Additional Information A brief description is: " The EMC6W201 is an environmental monitoring device with automatic fan control capability and enhanced system acoustics for noise suppression. This ACPI compliant device provides hardware monitoring for up to six voltages (including its own VCC) and five external thermal sensors, measures the speed of up to five fans, and controls the speed of multiple DC fans using three Pulse Width Modulator (PWM) outputs. " There is a PDF product brief, EMC6W201 Data Brief, available here: http://www.smsc.com/main/datasheets/6w201db.pdf As per SMSC, there is an evaluation board available; EVB-EMC6W201 is the EMC6W201 Evaluation Board. I presume that it would be similar to but, because of the newness of the EMC6W201 product, probably less robust than this one: http://www.smsc.com/main/catalog/emc6d102evb.html IOW, it might not include functional software. I have no idea if the company will provide the eval board for software development at no cost during some evalution period or if one has to buy the eval board. I did not find a way to purchase the eval board. I presume that means one has to complete a technical support form and request information: https://www2.smsc.com/mkt/intforms.nsf/faemail As far as testing goes, I, at least, probably would be willing to do that since I would very much like to have the output data available in Linux. Is anybody interested in working on this? Ric Johnson
