<p>PROBLEM TO BE SOLVED: To configure an information processor in which a second boot program basic part supported by an OS, which operates by a logical address is able to operate by using the function of a first boot program basic part supported by hardware, which operates by a physical address.SOLUTION: The information processor is configured to set a virtual address space in an arithmetic processing part and a control part including an address conversion mechanism, and to execute a start module for allowing the first boot program basic part which provides a first function on a virtual address space, and to execute a boot loader which instructs the reading of a boot object program by using a second function provided by the second boot program basic part, and to execute the second boot program basic part which receives the reading instruction from the boot loader, and to execute an emulation program for converting the reading instruction into a first function, and for transferring the first function to the first boot program basic part processing part, and to execute the first boot program basic part for transferring the reading instruction converted into the first function to the control part.</p> |
