发明名称 Operating speed control of a processor at the time of authentication before an operating system is started
摘要 According to one embodiment, non-volatile storage device stores a program for causing a processor to execute processing of determining whether registered authentication information exists in the information processing apparatus, authentication processing determining whether input authentication information matches the registered authentication information, and processing of booting an operating system. The operating speed control module decreases an operating speed of the processor in response to the determination that the registered authentication information exists in the apparatus, and increases the operating speed of the processor in response to the confirmation of the match between the input authentication information and the registered authentication information.

主权项 1. An information processing apparatus comprising: a processor; a non-volatile storage device configured to store a program for instructing the processor to execute when a basic input/output system (BIOS) is booted, (i) processing of, in response to power-on of the information processing apparatus, determining whether registered authentication information exists in the information processing apparatus, (ii) authentication processing of, when the registered authentication information exists in the information processing apparatus, comparing input authentication information with the registered authentication information and determining whether the input authentication information matches the registered authentication information, and (iii) processing of booting an operating system in response to confirmation of a match between the input authentication information and the registered authentication information by the authentication processing; and an operating speed controller configured to decrease an operating speed of the processor from a first operating speed to a second operating speed slower than the first operating speed in response to the determination that the registered authentication information exists in the information processing apparatus, and increase the operating speed of the processor to the first operating speed in response to the confirmation of the match between the input authentication information and the registered authentication information by the authentication processing before the operating system is booted.
