Abstract
PURPOSE:To shorten the rise time of an I/O device by executing retrying operation within a set prescribed time when the I/O device is not-ready at the time of initial program loading. CONSTITUTION:When a service processor 20 commands a central processing unit (CPU) 50 to travel the load routine of an initializing program, an initial program reading command is transmitted to the I/O device 30 through an I/O control device 40. When the I/O device 30 is not-ready, an I/O device state holding part 51 holds the information of the effect in its inside. When the contents of the holding part 51 is not-ready, the service processor 20 receiving end report from the CPU 50 reads out the value of a timer part 10, and when the value does not reach a limit value, the CPU 50 is allowed to start initial program loading again.
