Problems solved by technology

[0004] However, because the price of the memory chip is usually high, using two memory chips to store the BIOS program will increase the design cost of the system accordingly; in addition, in order to ensure that both chips can communicate with the system, in terms of hardware circuit design, For the two memory chips, the corresponding circuit structures need to be designed separately, which will increase the difficulty and cost of hardware design

Abstract

The embodiment of the present application discloses a BIOS redundancy backup method. Firstly, it is judged whether the first BIOS program is executed normally. Two BIOS programs; here the first BIOS program and the second BIOS program are stored in the same memory chip, but the storage location of the first BIOS program is different from the storage location of the second BIOS program. Compared with the redundant backup of the BIOS program using two memory chips in the prior art, the method provided by the embodiment of the present application uses only one memory chip to realize the redundancy of the BIOS program by jumping the execution address of the program. backup, thereby saving design and manufacturing costs.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a basic input output system BIOS redundancy backup method and device. Background technique [0002] The Basic Input Output System (BIOS) is a set of programs solidified on the memory chip of the mainboard of the computer, which stores important basic input and output programs, self-test programs after power-on and system self-starting programs. It can Read and write specific information about system settings from CMOS. The main function of BIOS is to provide the lowest and most direct hardware setting and control for the system. BIOS is used as the boot program of the system. Hardware server systems usually have high requirements on its reliability and stability. Once the BIOS program is abnormal, the server system will not be able to start and use normally. [0003] In the prior art, two memory chips are usually used to store the BIOS program to realize redundant b...
