Description

Method for Updating Partial Basic Input Output System

technical field

The present invention relates to a method for updating a basic input and output system, especially a method that can directly overwrite an image file provided by any hardware manufacturer or a standard setting organization in a memory storing a basic input and output system with an update software in a corresponding memory segment without having to rewrite the entire memory.

Background technique

The basic input and output system of electronic products (Basic Input Output System, referred to as: BIOS) belongs to "embedded software", which includes many basic programs for input and output of electronic products, and its characteristic is in the form of firmware. Stored in the read-only memory (such as: EPROM, EBPROM and FLASH, etc.) of electronic products, it is dedicated to functions such as drive, control processing, man-machine interface, and application programs. Compared with the operating system or application software, it is more closely related to the hardware. It is in charge of the settings of the central processing unit, memory, boot sequence, etc., and is the key to determining whether the hardware functions can be fully utilized. If any electronic product is replaced The basic input output system of the hardware device may not be able to activate the electronic product.

As far as the computer's basic input and output system is concerned, it controls the operation of the central processing unit (CPU) and each chip (Chip), as well as various standard peripheral devices (such as printers, mice, keyboards, hard drives and floppy drives) Operation. When a computer is activated and begins executing BIOS, the BIOS determines that all hardware is functioning correctly and then loads the operating system (OS) from the hard disk or disk drive into random access memory (RAM). Therefore, the operating system and the application program do not need to record the detailed information of the I/O device connected to it (such as: the address of the hardware). If the data changes, only the basic input and input system needs to be changed, and the operating system or application program does not need to be changed. .

In addition, new hardware and standards are constantly emerging. If new hardware is installed in the computer and the basic input and input system is implemented, the motherboard may not be able to correctly identify the new central processing unit (CPU), and cannot support large-capacity new hard disk, or the interface compatibility of sound card, display card, network card, etc. Support voltage adjustment, etc.), at this time, it is necessary to update the BIOS, in other words, if there is a new version of the BIOS, it is best to upgrade the BIOS, because updating the BIOS of the motherboard, It often means improved compatibility, enhanced functionality, and increased stability.

Also, if you want to update the basic input and input system, you must use some special update programs, and the update programs usually come from the manufacturer of the motherboard, and you can download the latest version of the update program from the website set up by the manufacturer, and then use the Execute the update program, and perform the update according to the steps indicated during the execution of the update program, so as to complete the update of the basic input and input system.

Furthermore, hardware manufacturers or standard-setting organizations provide various binary codes in order to make the hardware or standards they manufacture work normally, and the binary codes must be used by the manufacturer of the motherboard. After the editing program is edited, various subroutines in the basic input and input system will be formed, and the subroutines contain various hardware or standard operating information, so that after the basic input and input system is executed, the computer It will be possible to correctly operate each hardware and standard according to the operation information described above. Therefore, when any hardware manufacturer or standard setting organization changes the binary code, the manufacturer of the motherboard must input the basic output into the system. Corresponding hardware or standard binary codes are replaced with new binary codes, and then all binary codes are re-edited into new BIOS update programs.

The editing process of the update program of the above-mentioned new basic input and input system is not only time-consuming, but also if the wrong binary code is input during editing, or the compiling software is compiled incorrectly, the content of the update program will be wrong, and the update of the basic input and input system cannot be completed. This is a very troublesome thing for manufacturers.

In addition, the BIOS is stored in read-only memory, so updating the BIOS is not so easy compared to upgrading various other software, and if the updated version of the BIOS is wrong or the power is interrupted during the update, etc. Any reason will cause the update of the basic input and input system to fail, so that the computer cannot be activated. This situation is not irreparable, but the repair method is not something that ordinary users can complete. Therefore, how to complete the action of updating the basic input and input system in the shortest time and remove the action of re-editing the entire basic input and input system will be a matter of urgency.

Contents of the invention

In view of this, in order to improve the existing shortcomings, the inventor finally developed and designed a method for updating part of the basic input and output system of the present invention after long-term research and experiments.

An object of the present invention is to provide a method for updating part of the basic input and output system. An update software processes an image file to determine what kind of hardware or standard operating information the image file belongs to, and can directly Overwrite a corresponding storage segment in a memory storing the basic input output system to complete part of the update of the basic input output system, so that the user can obtain the new binary code provided by the hardware manufacturer or the standard setting organization After the image file, the update software can be used to directly update the hardware or the standard part of the basic input and output system without waiting for the motherboard manufacturer to re-edit the update program of the new basic input and output system.
