BIOS and UEFI: The Built-in Firmware that Coordinates PC Startup
The BIOS (Basic Input/Output System) and UEFI (Unified Extensible Firmware Interface) are essential firmware programs that play a critical role in coordinating the startup process of a PC.
The BIOS is a legacy firmware that has been used for many years in older computers. It is responsible for performing basic hardware initialization tasks, such as initializing and testing system components, loading the operating system into memory, and providing basic input/output services. The BIOS is typically stored on a small chip on the motherboard, called the CMOS (Complementary Metal-Oxide-Semiconductor) battery.
On the other hand, UEFI is a newer and more advanced firmware system that has replaced the traditional BIOS in modern computers. UEFI offers several advantages over the BIOS, including a graphical user interface (GUI), support for larger disk drives, faster boot times, and improved security features. UEFI also provides an environment for executing pre-boot applications, called UEFI applications, which can extend and enhance the functionality of the system.
In summary, both BIOS and UEFI are crucial components of the motherboard that enable the PC to start up and initialize the hardware and software components efficiently.
