BIOS是什麼?
Basic Input/Output System is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

The BIOS in modern PCs initializes and tests the system hardware components (power-on self-test), and loads a boot loader from a mass storage device which then initializes a kernel.

Most BIOS implementations are specifically designed to work with a particular computer or motherboard model, by interfacing with various devices especially system chipset. Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. In later computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.

Unified Extensible Firmware Interface (UEFI) is a successor to the legacy PC BIOS, aiming to address its technical limitations.
