The Basic Input Output System (BIOS) is responsible for enabling the hardware system on your computer when the computer is turned on. The BIOS Setup Utility makes it possible to change and store system configuration settings such as: which onboard components are enabled, the boot sequence for the system, and adjusting power management support.
To open the BIOS Setup utility, turn on the computer and immediately press the F10 key repeatedly, about once every second, until the BIOS setup utility screen opens.
Choose menu screens by pressing the left or right arrow keys. Use the up or down arrow keys to move up or down through the list of items on a menu screen. Press the Enter key to select an item for modification. For certain items, pressing the Enter key opens a submenu. After you have selected a menu item, use the arrow keys to modify the settings. Press the Esc key to exit from a submenu. Help is shown on the right side of the screen.
caution:Information stored by the Setup program is essential and changing certain settings can render your system unusable (until the BIOS is reset). BIOS settings should not be changed unless you are certain the change does not negatively impact the system.
