What is the BIOS ?

The Basic Input Output System, usually referred to as BIOS, is software stored on a small memory chip on the motherboard.

BIOS is sometimes incorrectly referred to as the Basic Integrated Operating System.

What is the BIOS Used For?

BIOS instructs the computer on how to perform a number of basic functions such as booting and keyboard control.

BIOS is also used to identify and configure the hardware in a computer such as the hard drive, floppy drive, optical drive, CPU, memory, etc.

How To Access BIOS

The BIOS is accessed and configured through the BIOS Setup Utility. The BIOS Setup Utility is, for all reasonable purposes, the BIOS itself. All available options in BIOS are configurable via the BIOS Setup Utility.

The BIOS Setup Utility is accessed in various ways depending on your computer or motherboard make and model. See How To Access the BIOS Setup Utility for help.

How To Use BIOS

BIOS contains a number of hardware configuration options that can be changed through the setup utility. Saving these changes and restarting the computer applies the changes to the BIOS and alters the way BIOS instructs the hardware to function.
