The BIOS, or basic input/output system, is a computer chip located directly on the motherboard. It controls some of the most basic functions of your PC, such as which drive boots up first and what the base time is for your PC. The type of motherboard you have installed in your PC dictates what keys need to be pressed to enter the BIOS setting mode. Once you access the BIOS in an Award-based motherboard, you can customise these settings.
Turn on or restart your PC to access the "POST" mode ("Power On Self Test").
Press the F2 button on the keyboard while your computer is in POST mode. This will bring up the BIOS option screen.
Use the up and down arrow keys on the keyboard to scroll between options, as your mouse will not work. When you get to "Advanced BIOS Settings" click the right arrow key.
Press the up and down arrow keys to continue scrolling through the advanced option menu, then use the "PgUp" and "PgDn" keys to change the value of the option listed. For instance, the "PgUp" and "PgDn" keys will change an advanced option from "Enabled" to "Disabled" or vice-versa.
Press the "F10" key to save the new settings, then press "Esc" to exit the BIOS.
