    • An information processing device includes: a nonvolatile memory having a program area storing a program for booting a system, and backup areas each storing a backup program identical in content to the program; a process executing unit that executes the program to perform a boot process of the system; an error detection unit that performs error detection on the program in parallel with the boot process; and a reboot unit that, when the error detection unit detects an error in the program, performs a recovery process to replace the program with one of the backup programs, and reboots the system using the replaced program. In the recovery process, the reboot unit refers to history information indicating a history of replacement of the program with the backup programs, selects the backup program used for the replacement from among the backup programs, and replaces the program with the selected backup program.
    • 信息处理装置包括:具有存储用于引导系统的程序的程序区域的非易失性存储器和每个存储与程序相同内容的备份程序的备份区域; 执行所述程序以执行所述系统的引导处理的处理执行单元; 错误检测单元,与所述引导过程并行地对所述程序执行错误检测; 以及重新启动单元,当错误检测单元检测到程序中的错误时,执行恢复处理以用其中一个备份程序替换程序,并使用替换的程序重新引导系统。 在恢复过程中,重新引导单元引用指示用备份程序替换程序的历史的历史信息,从备份程序中选择用于替换的备份程序,并用所选择的备份程序替换该程序。
