Description

This disclosure relates to a control system and method for a basic input/output system, as well as an expansion card. In recent technological advancements, engineers working with basic input/output systems (BIOS) face several significant challenges when modifying hardware settings during the motherboard's boot phase. First, the sheer size and complexity of BIOS code necessitates a deep understanding of its architecture and module details. This makes the process of precisely identifying the segments requiring modification a time-consuming and laborious task. Furthermore, hardware-related configuration code is often scattered across different modules, making the identification of the correct segments requiring correction even more difficult and time-consuming. Additionally, the BIOS compilation process is significantly longer than that of typical application software. This is because a full compilation is usually required for each change, lengthening the development cycle and reducing overall efficiency. Furthermore, testing and debugging present another significant challenge. Engineers need to flash a modified BIOS onto a test motherboard to verify its functionality. Even a minor error can cause the motherboard to fail to boot or result in unexplained errors. Debugging such issues is complex and time-consuming, often requiring multiple iterations of fixes and tests to ensure system stability. The contents of this disclosure will be better understood from the details described below and the accompanying drawings. These drawings are illustrative for illustrative purposes only and therefore do not limit the scope of this disclosure. Figure 1 is a block diagram showing the control system of the basic input/output system in an embodiment of the present disclosure.Figure 2 is a flowchart showing a control method for a basic input/output system in an embodiment of the present disclosure.Figure 3 is a block diagram showing the control system of the basic input/output system in an embodiment of the present disclosure.Figure 4 is a block diagram showing an expansion card in an embodiment of the present disclosure.Figure 5 is a block diagram showing an expansion card in another embodiment of the present disclosure. The following detailed description includes many specific details to fully understand the disclosed embodiments for illustrative purposes. Those skilled in the art will readily understand the concepts and features of the invention based on the description, claims, and drawings provided in the specification. The following embodiments further illustrate various aspects of the invention, but do not limit the scope of the invention. Refer to Figure 1. Figure 1 is a block diagram showing the control system of a basic input/output system in an embodiment of the present disclosure. As shown in Figure 1, the control system 1 includes a motherboard 11, a shared memory 12, and a processing unit 13. The motherboard 11 is connected to the shared memory 12, and the shared memory 12 is connected to the processing unit 13. The processing unit 13 may be connected to the motherboard 11 via the shared memory 12. The motherboard 11 includes a basic input/output system (BIOS) 111. The motherboard 11 is configured to execute user-inputted operation commands, which may be configured to change the hardware settings of the BIOS 111 or to read data from the BIOS 111. Specifically, the operation commands may be configured to change the hardware settings of the BIOS 111 boot-up process, but this disclosure is not limited thereto.
