BIOS is an acronym for Basic Input Output System, and its Chinese name is "Basic Input Output System". It is an industry-standard firmware interface on IBM?PC-compatible systems. The term BIOS first appeared in 1975 in the CP/M operating system. BIOS is the first software loaded when a personal computer boots.

In fact, it is a set of programs solidified onto a ROM chip on the motherboard inside the computer, which holds the most important programs for the computer's basic inputs and outputs, the self-testing program after powering on the computer, and the system's self-boot program, which reads and writes specific information about the system's settings from the CMOS.? Its main function is to provide the computer with the lowest-level, most direct hardware settings and control. In addition, BIOS provides some system parameters to the operating system. Changes to the system hardware are hidden by the BIOS, and programs use BIOS functions rather than controlling the hardware directly. Modern operating systems ignore the abstraction layer provided by the BIOS and directly control hardware components.
