Apparatus for restoring setting information of a board management controller from a backup memory before loading an OS when a system board is replaced

An information processing device, comprising:

• a processing circuit that processes information by using an operating system (OS);
• a management circuit that is independent of the processing circuit, performs status management of hardware including the processing circuit, and includes a management memory in which setting information of the management circuit is stored;
• and
• a backup memory into which setting information of the management circuit stored in the management memory is copied as management backup information by the management circuit and from which the management backup information is extracted by the management circuit, the backup memory being physically connectable to and removable from the management circuit, wherein
• the management circuit operates to perform the status management even when the processing circuit is not started up, and copies the setting information of the management circuit stored in the management memory as the management backup information in the backup memory even when the setting information stored in the management memory is changed while the processing circuit is not started up, and
• the management circuit reads the setting information from the backup memory to restore the setting information in the management memory and then the processing circuit starts the operating system (OS).
