Abstract:
1. A method of detecting a failure when installing an I/O controller in a computer system having a processor and a memory connected to the I/O controller, the method comprising the steps of: when starting installation of the I/O controller, the processor searching the memory for memory blocks related to operation of the I/O controller, the processor testing each of the memory blocks related to operation of the I/O controller by executing a pseudo-I/O instruction in which bidirectional communication occurs between the I/O controller and a respective one of the memory blocks, and the processor evaluating a response to the pseudo-I/O instruction, so long as the response received by the processor is normal, the processor repeating the testing step until all memory blocks related to operation of the I/O controller have been tested, and then installing the I/O controller, and when the response received by the processor is abnormal, stopping the testing step and stopping installation of the I/O controller.
