Method for updating and recovering system by bootstrap program

Abstract

It is a method to guide the program update and recover system. When the computer system runs guiding program update, it is to use the flag value enactment to determine update program status. Before the computer system starts and runs BIOS, it is to judge the guiding program status and self-recover the guiding program to finish the start through the means of comparing and detecting the flag value.

Description

technical field [0001] The present invention relates to a system and method for detecting update and restoration, in particular to a system and method for executing boot program update and restoration by setting and detecting flag values ​​on computer systems. Background technique [0002] The basic input / output system (BIOS) is an important program for the computer system to start and run, and whether the boot program that the BIOS needs to use during execution can meet the hardware requirements of the computer system, or whether it can be completely and normally started and executed also affects The most critical factor in the startup and operation of a computer system. [0003] Because the hardware in the computer system is improving day by day, it is often necessary to replace the old version of the boot program and provide a new boot program to enable the new hardware to play its maximum effect; The phenomenon of interrupting the operation occurs due to some factors, w...

Problems solved by technology

[0003] Because the hardware in the computer system is improving day by day, it is often necessary to replace the old version of the boot program and provide a new boot program to enable the new hardware to play its maximum effect; The phenomenon of interrupting the operation occurs due to some factors, which leads to the damage of the stored boot program or the boot program being updated, which will cause the computer system to fail to start and run normally. Therefore, it is necessary to set the update or recovery of the boot program in the computer system. mechanism

[0004] There are many ways to update the boot program in the past, the simplest is to take the traditional way, that is, to replace the entire read-only memory (BIOS ROM) that stores the boot program, and replace it with a read-only memory that contains a new boot program, but This method not only needs to spend additional purchase cost, but also is quite complicated in the update program, which often causes inconvenience to the user; and in the recovery method of the boot program, it is common to use multiple boot programs installed in the computer system at the same time. Read the memory, and then realize the purpose of restoring the boot program by means of circuit judgment

[0005] However, in the above-mentioned existing methods, additional costs must be added to purchase hardware for storing the new boot program. Whether these costs are paid by the user or absorbed by the manufacturer when manufacturing, in fact, it will usually be in the long run. It is not a small burden; and in addition to the additional cost, sometimes the user cannot know the status in the first time because of the damage of the boot program, which leads to the need to spend time to judge and detect when starting the computer system , wasted time
