Patent number: 7631224Abstract: To completely perform a memory data collecting process by a panic dump in the event of failure, in the configuration information about main memory 5 announced to an operating system by boot firmware, different areas (first main memory area and second main memory area) are set between activation of an operating system in a system operation mode and activation of an operating system in a dump operation mode. In the event of failure, activation is performed in the dump operation mode and a dumping process is performed with memory information in the event of failure maintained.Type: GrantFiled: December 28, 2004Date of Patent: December 8, 2009Assignee: Fujitsu LimitedInventor: Yukio Oguma
