The present invention provides a high reliability fault tolerant computer system capable of constructing a redundant configuration employing PnP software. In duplexing systems, entities of IO bridges (actual IO bridges) which are connected to virtual bus and correspond each other is integrated into the systems as pseudo IO bridges, so that if the systems are physically disconnected each other, by emulating the actual IO bridge in another system, the pseudo-IO bridge can act as if a so-called PnP event in the IO bridge itself does not occur.
