Abstract: A device causing a faulty condition in a computer system having devices is isolated by detecting for a faulty condition associated with the devices and identifying the device causing the faulty condition. The devices are coupled to a bus. The faulty condition includes a bus hang condition. The devices are turned off when a bus hang condition is detected. The devices are then turned back on to test the devices. Each device is tested by writing and reading its configuration space. Information on the bus associated with the faulty condition is stored. The stored information is retrieved after the faulty condition has occurred, with the stored information including address, data, and bus control information.

Abstract: PROBLEM TO BE SOLVED: To isolate a device where a fault has occurred by discriminating the device in the faulty state by a fault isolation controller in response to a fault state. SOLUTION: A system controller/host bridge circuit 18 controls access to a system memory 20, which is coupled with a local bus 22 together with a CPU 14 and a level-2/cache (L2 cache) 16. Information that a nonvolatile random access memory(NVRAM) 70 holds, does not volatilize even when the computer system is powered OFF. Then, an automatic server recovery(ASR) timer 72 monitors inactive operation of the computer system. When the system is locked up, the ASR timer 72 turns off about 10 minutes later. Then a keyboard controller 21 monitors a keyboard 19 to detect a depressed key.
