Embodiment Construction

[0038] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals are used in the drawings and description to refer to the same or like parts.

[0039] Please refer to figure 1 , figure 1 A schematic diagram of an electronic device according to an embodiment of the present invention is shown. The electronic device 100 includes a first controller 110 , a second controller 120 and a Basic Input / Output System (BIOS) 130 . The first controller 110 is used for receiving the boot code BTCODE, and provides the boot code BTCODE to enable the electronic device 100 to perform a boot action. The basic input output system 130 is coupled to the first controller 110 . A first transmission path PA1 may be formed between the BIOS 130 and the first controller 110 . The BIOS 130 can provide the boot code BTCODE to the first controller 110 through t...

Abstract

The invention provides an electronic device and a power-on method thereof, which can effectively execute power-on action. The electronic device comprises a first controller, a basic input / output system and a second controller. The first controller is used for receiving the power-on code and providing the power-on code to enable the electronic device to execute a power-on action. The basic input / output system is used for providing a power-on code. The second controller is provided with at least one communication interface. The at least one communication interface is used for connecting at least one external device. The at least one external device provides a backup power-on code to the second controller. When the electronic device fails to start up according to the start-up code provided by the basic input / output system, the first controller changes to receive the backup start-up code and provides the backup start-up code to enable the electronic device to execute the start-up action.

Description

technical field [0001] The present invention relates to an electronic device and a booting method thereof, in particular to an electronic device and a booting method thereof that can assist the booting action through external data. Background technique [0002] In today's electronic devices, a read-only memory implementing a basic input output system is mostly required to store the contents of the firmware program. However, once the ROM as the basic input output system is damaged, the electronic device cannot read the correct firmware boot code and cannot start normally. [0003] In the known technology, redundant read-only memory is often provided on the motherboard to provide backup firmware boot codes. Such practices often require multiple product costs. And the read-only memory as a backup also has the problem of corruption. It is not guaranteed that the electronic device can be turned on normally. SUMMARY OF THE INVENTION [0004] The present invention is directed...
