The BIOS (Basic Input/Output System) is a firmware interface that initializes the computer hardware during the boot process. It provides a way for the operating system to communicate with the hardware, and it also stores the computer’s hardware configuration settings.
Being able to access and change the BIOS settings can be useful for troubleshooting computer problems, upgrading hardware, or overclocking the system. However, it’s important to note that making changes to the BIOS settings can also be risky, so it’s important to proceed with caution.
