What is bios chip?

A BIOS chip (Basic Input/Output System chip) is a small, non-volatile memory chip on a computer's motherboard that stores basic system information such as system settings, boot parameters, and hardware configurations. The BIOS chip is responsible for initializing and testing the computer hardware components during the boot-up process. It provides the necessary instructions for the operating system to load and communicate with the hardware.

The BIOS chip is typically a flash memory chip that can be reprogrammed or updated by the user to fix bugs, add new features, or improve compatibility with newer hardware. This process is known as flashing the BIOS.

In modern computers, the BIOS chip is gradually being replaced by the Unified Extensible Firmware Interface (UEFI), which provides more advanced features and security options. However, BIOS chips are still commonly found in many older computers and legacy systems.
