Hi! As you pointed out you need to get to that enable register. This register is > provided in PCI address space. > To access it you need to its base address.

First of all thank you very much for the very quick response! Unfortunately the patch does not work. I have read the value in the register even before we write anything to it and the value stored is 0x1000f00 which means that bit 3 is 0 and therefore the SMBus controller should be enabled. So there must be some other means of enabling it. Under windows I have seen that the software Everest Home enables the controller and it works so there *is* a way of enabling it...
