Description of the Invention: [Technical Field] The present invention relates to a computer system and method for switching a basic input/output system (BI〇s), and more particularly to a computer for BIOS switching using a power button System and method. [Prior Art] Basic Input Output System (BIOS) is used in the computer to record the communication mode between each chip on the motherboard and the control chip, and other related settings related to the boot process, so that the user can Yuancheng started the operation and entered the operating system. Therefore, BI〇s is an integral part of the computer system. Therefore, if the BI0S data is damaged due to operational factors such as virus infection or improper update, it will seriously affect the computer system related boot process. The conventional method for solving the above problem is to store the BI〇s data in the basic round-in and output system read-only memory (BI〇SR〇M)*, and divide the δ-resonation used to store the data into two parts, part of which is The system is generally turned on, and the other part is used as a backup, and then the memory is switched by the software. However, this method usually requires BI资料s R〇] the complete information of the start-up area in the VI can only start the system and switch the action. If the tributaries in the start-up area are completely damaged, the rescue purpose cannot be achieved. In addition, there are other solutions on the market, such as jumper jumpers on the motherboard, so that BI0S can accept the requirements for updating data. However, this practice still requires the user to obtain the full BIOS update 5 1332177 content, so it is very cumbersome and complicated for the user. Therefore, a simpler BIOS switching method is needed, so that the user can easily solve the problem that the BIOS cannot be booted properly due to the destruction of the BIOS data, and the purpose of BIOS rescue is completed.
