Embodiment Construction

[0054] The implementation of the present invention will be described in detail below with reference to the drawings and examples, so as to fully understand and implement the implementation process of how to use technical means to solve technical problems and achieve technical effects in the present invention.

[0055] A dual BIOS system based on Feiteng platform, the design steps include:

[0056] First, use the Phytium processor to access the chip select signal of the BIOS chip, and realize the dual BIOS system mechanism of the Phytium platform motherboard by switching the connection circuit;

[0057] Secondly, by adding the CRC check information and the BIOS system synchronization module to the executable file of the BIOS system, the BIOS synchronization module is executed in the BIOS when the power is turned on or reset, which can ensure that the main and backup BIOS systems are completely consistent; when one of the BIOS When the system data is damaged (but the chip storin...

Abstract

A dual BIOS system based on a Feiteng platform is provided. The system comprises a Feiteng processor, a switch connection circuit, a BIOS_1 system, and a BIOS_2 system. The Feiteng processor controlsthe two BIOS systems through the switch connection circuit and a chip select signal. The online upgrade and synchronization process can be implemented on the system, and the synchronization process comprises power-on synchronization and reset synchronization. The technical scheme of the present invention has the beneficial effects that the problem of possible inconsistency of the dual BIOS systemcontent in the Feiteng platform can be solved, and the online upgrade problem of the BIOS system in the Feiteng platform and the possible out-of-synchronization problem of the upgraded dual BIOS system can be solved.

Description

technical field [0001] The invention belongs to the technical field of basic input and output systems, and in particular relates to a dual BIOS system based on a Feiteng platform and an implementation method thereof. Background technique [0002] BIOS: BIOS is an acronym for "Basic Input Output System" in English. After literal translation, the Chinese name is "Basic Input Output System". It is a set of programs solidified on a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, the self-test program after power-on and the system self-starting program. It can read and write system settings from the CMOS. specific information. Its main function is to provide the computer with the lowest and most direct hardware setting and control. In addition, BIOS also provides some system parameters to the operating system. Changes to system hardware are hidden by the BIOS, and programs use BIOS functions instead of ...
