ABSTRACT:
A fault tolerant (FT) computer system includes a primary system and a secondary system. The primary system includes a first CPU; a first FT control section connected with the first CPU; and a first south bridge connected electrically and operatively with the first FT control section. The secondary system includes a second CPU; a second FT control section connected with the second CPU; and a second south bridge connected electrically with the second FT control section and not connected operatively with the second FT control section. The first FT control section and the second FT control section are connected by a link section, and the primary system and the secondary system operate in synchronization with each other by using the link section, except for the second south bridge.
