First, sorry, I don t really understand Russian

First, sorry, I don't really understand Russian very well. But, If you are asking about the SMBus base address, I can say that it depends on the chipset and the BIOS. In most case, the southbridge have a register that act as the SMBus base address register. Very often this register is programmable. And it's programmed by the BIOS during BIOS execution.
