Description
本发明有关在一包括双基本输入输出系统(BIOS)存储装置的计算机系统中以一安全回复BIOS存储装置来自动回复一主BIOS存储装置，以避免计算机系统的开机时的启动运作发生错误而导致计算机开机失败的方法。The present invention relates to a computer system including a dual basic input output system (BIOS) storage device with a safe recovery BIOS storage device to automatically restore a main BIOS storage device, so as to avoid errors in the startup operation of the computer system when it is turned on. How to computer fail to boot.
在现今计算机的架构中，基本输入输出系统(basic input-output system，BIOS)是计算机基本操作中最基础的软件。BIOS主要是由计算机低阶的指令集所组成，提供计算机运作时最基本的硬件测试、定义计算机的特性并处理基本的工作。比如：当计算机开机时，执行计算机的开机自我测试，诠释键盘所发出的信号，与连接端口间信息的传递等等。因此，计算机一开机时初始的运作，皆是依照BIOS的内容来执行运作。倘若BIOS出现问题，计算机一开机便无法执行如内存(RAM)、硬盘(HD)、中央处理器(CPU)等的测试，则计算机便无法顺利地开机。In today's computer architecture, the basic input-output system (basic input-output system, BIOS) is the most basic software in the basic operation of the computer. The BIOS is mainly composed of the computer's low-level instruction set, which provides the most basic hardware testing, defines the characteristics of the computer and handles basic tasks when the computer is running. For example: when the computer is turned on, it executes the computer's boot self-test, interprets the signal sent by the keyboard, and transmits information with the connection port, etc. Therefore, when the computer is turned on, the initial operation is performed according to the contents of the BIOS. If there is a problem in the BIOS, the computer cannot perform tests such as memory (RAM), hard disk (HD), and central processing unit (CPU) once it is turned on, and the computer cannot be turned on smoothly.
也因为BIOS在计算机系统中具备了如此重要的地位，一般都会将BIOS的程序指令集快速存储在一个可以长久不需电源的内存中，如Flash ROM、PROM、EPROM、EEPROM等，并将此类BIOS内存内建于计算机的主机板或放入计算机系统的芯片组中，使其内容不受电源供电影响而可永久保存其内容。Also because the BIOS has such an important position in the computer system, the program instruction set of the BIOS is generally quickly stored in a memory that can last for a long time without power supply, such as Flash ROM, PROM, EPROM, EEPROM, etc., and such The BIOS memory is built into the motherboard of the computer or placed in the chipset of the computer system, so that its contents can be permanently stored without being affected by the power supply.
然而，BIOS内存的内容并非是完全没有错误的。当BIOS内存的电路结构随着时间而产生退化(degradation)或是受到不可预测的操作的影响，其内容可能会流失或产生错误，导致计算机开机执行BIOS程序时产生失误，因而导致计算机无法完成开机。However, the contents of BIOS memory are not completely error-free.

See Figure 2. The method for automatically safely restoring the BIOS storage device of the present invention starts from step 21. After the computer system is turned on (step 22), the GPIO pin of the chip power-on circuit will make the safe recovery BIOS storage device energized (step 23). At this point, the error detection circuit of the computer will check whether the BIOS program stored in the main BIOS storage device contains errors (judgment formula 24). The technology of error detection can be judged by checking whether a checksum (checksum) data value or a parity check (parity check) data value or a cyclic redundancy check (CRC) data value located at a predetermined storage address of the main BIOS storage device are correct. Whether the contents of the main BIOS storage device contain errors. If the error of any main BIOS storage device content is not detected, the GPIO pin of the chip power-on circuit will make the safe recovery BIOS storage device power off and the main BIOS storage device will be powered on (step 26), and the computer boot operation will be performed by the main computer. BIOS storage device to continue (step 27). If it is detected that the content of the main BIOS storage device contains errors, the quick program stored in the main BIOS storage device or the safe recovery BIOS storage device will be executed, so that the BIOS program stored in the safe recovery BIOS storage device will be reprogrammed into the main BIOS storage device, thereby restoring the content of the main BIOS storage device (step 25). After the reprogramming step is completed, the GPIO pin of the chip power-on circuit will make the safe recovery BIOS storage device power off and the main BIOS storage device will be powered on (step 26), and the computer booting operation will be continued by the main BIOS storage device Proceed (step 27). In this way, the booting procedure of the computer system can be successfully completed without being affected by whether the BIOS program stored in the main BIOS storage device contains errors.
综上所述，本发明利用一个与主BIOS存储装置分别储存一BIOS程序的安全回复BIOS存储装置来做为当主BIOS存储装置被检测包含错误时的安全回复装置，并且将快速程序一并储存于主BIOS存储装置或安全回复BIOS存储装置中，使得主BIOS存储装置的内容被检测出错误时，执行所述快速程序以安全回复BIOS装置所储存的BIOS程序来回复主BIOS存储装置的内容。这样的方法可以避免BIOS程序执行时发生错误而导致计算机无法开机的结果，使计算机的启动运作得以顺利进行。In summary, the present invention utilizes a security recovery BIOS storage device that stores a BIOS program separately from the main BIOS storage device as a security recovery device when the main BIOS storage device is detected to contain an error, and stores the quick program in the In the main BIOS storage device or the safe recovery BIOS storage device, when an error is detected in the content of the main BIOS storage device, the fast program is executed to recover the contents of the main BIOS storage device by executing the BIOS program stored in the safe recovery BIOS device. Such a method can avoid the result that the computer cannot be turned on due to an error during the execution of the BIOS program, so that the startup operation of the computer can be carried out smoothly.
