Abstract
An information processing apparatus includes a BIOS storage unit that stores at least a Basic Input Output System (BIOS) program, a main controller that starts up an operating system by executing the BIOS program, and a sub-controller that manages peripheral apparatuses and accesses the BIOS storage unit, in which the sub-controller includes a digest computation unit that computes a digest value on the basis of BIOS program data stored in the BIOS storage unit in parallel to execution of a process in the main controller, and in which the main controller determines validity of the BIOS program on the basis of the digest value.
