I haven't used mbmon in a while, maybe there is a way to ask it to try using a different address for LPC (ISA) IO access method. The address could be discovered using superiotool (from ports) and the chip's documentation. However, I am not confident that mbmon knows enough about that specific chip (IT8728F). -- Andriy Gapon
