In a BIOS storing and controlling system, a hard disk storing BIOS data in a predetermined area. A system controller produces and supplies, at a time of input of a power source, an initial signal to the central processing unit. The central processing unit is held at an initial state from reception of the initial signal until reception of an initial state release signal. A hard disk controller and a memory controller transfers the BIOS data of the hard disk to a main memory device in a time interval of the initial state of the central processing unit. The hard disk controller produces and supplies the initial state release signal through the system controller to the central processing unit after transfer of the BIOS data. The central processing unit starts to access the main memory device when the central processing unit is supplied with the initial state release signal from the hard disk controller.
