UNDERSTANDING BIOS AND ITS FUNCTIONS

WHAT IS BIOS AND ITS FUNCTION

The BIOS is short for the Basic Input Output System, which is simply a program contained in a Flash Memory made from CMOS (Complementary Metal Oxide Semiconductor), which is tasked to regulate the basic functioning of a computer hardware device.

In more detail, the BIOS functions include:

  • Recognizing hardware installed on a computer’s motherboard, such as hard disk and memory capacity installed
  • Initializing when the computer is powered On is known as Power On Self Test (POST)
  • Set Basic Computer Configuration such as boot sequence, date, power management, basic settings for other hardware
  • Locate the boot location, and prepare for the operating system to run.

BIOS has long been used in the PC industry and still runs in real mode (real-mode) slow, then the PC designers agreed to replace the BIOS with a better IE EFI (Extensible Firmware Interface) derived from the Itanium architecture – Wikipedia
