Now you would need to take a look at your (physical) board again and note the name of the four chips that are pointed on the picture. I guess that B1 will be the ADM1027, whils A1 and A2 would be secondary chips (ADM1032 maybe?). No idea what B2 could be though. > How can I explain the concept of "activating the AMD-8111 SMBus" to > him? What do you need - memory locations to address the chip with? Modern computers are mostly made of PCI devices. This is what lspci lists. Each device has one or more "functions" (understand: sub-devices). Devices also belong to a group or bus. This is the meaning of the three values in front of lspci's line. For example, "00:09.0" means bus 0, device 9, function 0. In your specific case your lspci shows: (...) 00:07.1 Class 0101: 1022:7469 (rev 03) 00:07.3 Class 0680: 1022:746b (rev 05) (...) The AMD-8111 SMBus function has PCI ID 1022:746a. It should obvously show between the two other lines as function 2 of PCI device 7 on bus 0. But it does not. It is almost certain that this function *is* here (because the device is, and you cannot easily remove a function from a given device). It it doesn't show up, this is because the BIOS has been told to remove it from the PCI devices list. The reason why manufacturers sometimes do this are obscure. One often heard reason is that it would frighten Windows user because it would appear as a unknown device in the System panel. Anyway, we had to deal with similar behaviors on some ALi and Intel chipsets so far. Never with AMD. Usually, the solution it to change the value of some bits in some place. The question is: which bits, which place. We cannot guess that without documentation. So basically you need to ask them what operation is needed to re-enable that specific PCI function. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
