1. An information processing apparatus for performing a system boot by using programs stored in a non-volatile storage device, the apparatus comprising:

  • a CPU;

    a non-volatile first storage device for storing, as programs to be executed by the CPU, a bootstrap program having a first check code assigned thereto and a main program having a second check code calculated by a method different from that used for calculating the first check code;

    a volatile second storage device for storing the program read from the first storage device; and

    a transferer for reading a program stored in the first storage device,wherein during system boot, the transferer reads the bootstrap program from the first storage device, subjects the bootstrap program to an error detection/correction process based on the first check code, and transfers the processed bootstrap program to the second storage device.
