Support details

This information applies to HP and Compaq desktop computers.

This document contains information on what the BIOS program is and how to use the BIOS Setup utility.

Your computer includes a BIOS Setup utility for changing important computer settings. This document

does not define specific default BIOS settings because too many differences exist between computer

models. This document includes typical examples. Your system might be different.

If you are looking for information on updating the BIOS, see Updating the BIOS .

Use the BIOS Setup utility to change important BIOS settings for the computer. Basic Input/Output

System (BIOS) is a program that controls communication between all input and output devices on the

computer (such as disk drives, display, keyboard, mouse, and printer). The BIOS settings are stored

in a chip on the motherboard CMOS (Complementary Metal Oxide Semiconductor) memory. A battery

on the motherboard keeps the settings from being lost when the system is turned off.

The BIOS stores configuration information such as:

The addresses of devices (hard disk drives, for example), that are attached to the

computer.

The startup sequence of the computer.

The amount of system and extended memory.

CAUTION: The information stored by the BIOS Setup utility is essential for correct

computer operation. Do not change settings without understanding what will

happen. Use caution when making changes in the BIOS Setup utility. A mistake

could prevent the computer from operating correctly or Windows from opening.

To open the BIOS Setup screen:

Turn off the computer and wait five seconds.1.

Turn on the computer.2.

When the first screen displays, immediately press the key if your computer was

built in 2006 or later (came with Vista or Windows 7). Press the key if your computer

was built before 2006 (XP or earlier). Press the key once every second until a BIOS

Setup utility screen opens.

NOTE: On some Compaq Presario computers (before 2002), press the key at

the logo screen.

Use the keyboard to move through the menus.4.

Help is displayed on the right side or bottom of the screen.
