Abstract:
According to one embodiment, a system program determines whether a boot mode of an information processing device is set to a first mode for booting an operating system from a storage device initialized by a master boot record (MBR) or a second mode for booting an operating system from a storage device initialized by a GUID partition table (GPT). The system program enables a first or second trusted platform module based on a result of determination of the boot mode.
