Abstract: A safety booting method for an embedded controller is applied in a laptop. The embedded controller is installed in the laptop, and the laptop includes a central processor unit (CPU). The safety booting method for the embedded controller includes steps of: connecting the embedded controller with a power; determining whether a safety verification for a booting read only memory (ROM) is passed or not; and initializing the power of the laptop by the embedded controller to normally provide the power to the laptop and boot the laptop when the safety verification for the booting ROM is passed.

Abstract: A display method for logo graphics displayed on a screen is provided, implemented by a smart device. The display method includes the following steps: powering on the smart device, to enter a Basic Input Output System (BIOS) stage; accessing, from a first non-volatile memory of the smart device, exclusive logo graphics data private-key encrypted for decryption, and using a public key pre-stored in a second non-volatile memory of the smart device for verification; and displaying, when the public key matches a private key corresponding to the exclusive logo graphics data, an exclusive logo graphic on a screen according to the decrypted and decompressed exclusive logo graphics data. The present invention further includes a smart device, a readable record medium, and a computer program product.
