Study Notes
BIOS Overview
- The BIOS (Basic Input/Output System) is a type of firmware used in a computer system to control and provide a interface between the operating system and the computer hardware.
Origin of BIOS
- The BIOS was originally used in the CP/M (Control Program for Microcomputers) operating system.
Role of BIOS
- The role of the BIOS is to initialize and test the computer hardware components, and to provide a set of low-level routines for the operating system to use.
- The BIOS acts as an intermediary between the operating system and the hardware, providing a standardized way for the operating system to access the hardware components.
BIOS in Modern PCs
- In modern PCs, the BIOS is responsible for booting the operating system, configuring the hardware components, and providing a setup utility for the user to configure the system settings.
BIOS in UEFI-based Systems
- In UEFI (Unified Extensible Firmware Interface) based systems, the BIOS is replaced by the UEFI firmware, which provides a more advanced and flexible way of managing the system hardware.
- The UEFI firmware provides a more secure and reliable way of booting the operating system, and also provides additional features such as support for networking and graphics.
