Patent 8001368 was granted and assigned to NEC Corporation on August, 2011 by the United States Patent and Trademark Office.
A generator generates configuration information of a virtual hardware unit based on configuration information in a PCIBOX. The generator generates recognition information for recognizing the virtual PCIBOX as a PCIBOX that is connected with a slot from the configuration information of the virtual PCIBOX. When PCIBOX is connected with the slot, the generator overwrites the configuration information in PCIBOX with the configuration information of the virtual PCIBOX.
