Hi Jean, > Thanks for the proposal. Basically we want to know what hardware > monitoring chips are used in the system, and how they are wired. I > suspect that HP uses a non-standard I2C bus, possibly GPIO-driven. If I'm not totaly mistaken it's all controlled by the proprietary iLO ASIC which shows up as a PCI device. I don't know the interface to that beast and how temp and sensors are connected to it. I'll check the schematics as soon as I have established connection to the HP intranet. I'm currently slacking away in Switzerland but am supposed to work remotely... :-) Not a big deal until it starts snowing... ...juerg > Thomas, I've thought a bit more about your problem, and I'm now almost > certain that you won't find anything attached to your motherboard's > SMBus, even if you upgrade the BIOS or force the SMBus base address. > You said that the "hplog" utility was printing temperature values, so > it must get them from somewhere, and it definitely can't get them from > anything connected to the currently disabled SMBus.
