What is the main function of BIOS?

A computer’s Basic Input Output System and Complementary Metal-Oxide Semiconductor together handle a rudimentary and essential process: they set up the computer and boot the operating system. The BIOS’s primary function is to handle the system setup process including driver loading and operating system booting.

What are the four functions of a BIOS?

The 4 functions of BIOS

  • Power-on self-test (POST). This tests the hardware of the computer before loading the OS.
  • Bootstrap loader. This locates the OS.
  • Software/drivers. This locates the software and drivers that interface with the OS once running.
  • Complementary metal-oxide semiconductor (CMOS) setup.
