<P>PROBLEM TO BE SOLVED: To acquire sufficient information for analyzing a factor that causes a failure in starting even when the frequency of occurrence is low. <P>SOLUTION: A CPU 1 carries out a program stored in a flash ROM 4 (a device initialization and self-diagnostic program) by reset release after power-on. Most of the area (a first area) of the flash ROM 4 is used by a BIOS (basic input/output system), and the start date and time, progress information of initialization processing and self-diagnostic processing, environmental information, etc. are stored in a second area together with processing numbers. When preceding incomplete processing is detected, detection data is copied into a third area from the second area, and time-out status information and device configuration related to the data are also stored in the third area. Based on each processing number held in the second area, incomplete processing is detected, and the detected data, time-out status information, device configuration, etc. are copied in the third area. Only the information in occurrence of a fault is thereby stored, and the factor of the starting failure can be specified. <P>COPYRIGHT: (C)2009,JPO&INPIT |
