[Prior Art] BIOS (Basic Input/〇utput System) is a kind of boot control unit required for various computer platforms. It is usually integrated with the central processing unit: it is integrated on the host circuit board to provide the computer platform. - Group boot control functions, including initializing various hardware components and peripheral devices, performing POST, and self-testing programs, and loading the operating system code. Basically, the main reason for deleting the control unit is to let the hardware circuit of the computer platform be controlled by the operating system. However, in practical applications, BI 〇s swim + say that a + private code is often possible due to the peak finger The situation of the destruction caused the computer to be flat and the u-amp; This is the solution. The first one is to solve the problem] There is a kind of solution for the two identical BIOS ports on the host circuit board, Gans, defeated and set 2 (four) s day and day 'one of them as a film, The other one is used as a backup. When the chip fails, the chip will be replaced. The domain milk chip can replace it to make the 19819 5 200823652 two-knowledge platform still function. However, the disadvantage of this approach is that loading two wafers will significantly increase the hardware cost. The second solution is to divide the storage space of a single wafer: : area i or to store two identical _ programs. As the master BI 〇 S code, and the other as the 耘 code. However, a disadvantage of this method is that when the circuit and the switching control mechanism are needed, the master control code is used in the master control code: / ί, the control function is switched to the backup process, and the 4 Difficult and increase the cost of design.

In a specific implementation, the modules 110, 12, 13 are, for example, integrated into a pre-planned backup processing code storage area 43 in the BI0Sfg machine control unit 4 as shown in FIG. And when the computer platform is powered on, first execute the J code of the storage port of the backup processing code storage area 43. The following are the first to explain the individual attributes and functions of these modules 11〇, 12〇, and (10). 19819 9 200823652 The initialization code checking module 110 can respond to: when the power of the computer platform is started or reset (that is, when a startup event 2G1 occurs), check: the initialization code of the BIOS boot control unit 4 Whether the initialization code stored in the storage area (Boot Block) 41 is intact, and if not, the -initialization code error message is sent to the initialization code recovery module 130'. If yes, the initialization program is issued. The code normal message causes the central processing unit (CPU) 30 to first execute the code stored in the initialization code storage area 41 in the BI0S boot control list = 40, and then execute the program stored in the official code storage area 42. Code to complete the boot process. In a specific implementation, the initialization code checking module 11 uses, for example, a checksum to check whether the initialization code stored in the initialization code storage area 41 is intact. The backup initialization code storage module 预2〇 is used to pre-store a backup initialization code, that is, the initialization code stored in the initialization code storage area 41 of the BI〇s boot control unit 4〇. The backup initialization code storage module 12 can be, for example, a storage segment in the backup processing code storage area 43 or another storage device, such as a compact disc. The initialization code recovery module 13 can execute an initialization code recovery program in response to the initialization code exception message sent by the initialization code checking module 110 to initialize the backup code storage module 120. The pre-stored backup initialization code is copied or downloaded and written to the initialization code storage area 41, thereby restoring the corrupted code. 10 19819 200823652 : The backup processing program can be used in the _ area 43 • 2: Γ that is, the computer platform initialization code jumper (jumpers) of the present invention is used to prevent the picking of the hardware group.

If yes, initialize the code check mode, group 110 will send a normal message to initialize the private code to start the boot process (as shown in Figure 4). Where m is shown in the action 2, the code stored in the initialization code 2 memory area 41 in the boot control unit 40 is executed to complete the initialization process (such as the processing operation shown in Fig. 21). Then, the process of storing and storing the code storage area 42 is executed.
