2.2 BIOS setup program
This motherboard supports a programmable Serial Peripheral Interface (SPI) chip that you
can update using the provided utility described in section 2.1 Managing and updating your
BIOS.
Use the BIOS Setup program when you are installing a motherboard, reconguring your
system, or prompted to “Run Setup.” This section explains how to congure your system
using this utility.
Even if you are not prompted to use the Setup program, you can change the conguration of
your computer in the future. For example, you can enable the security password feature or
change the power management settings. This requires you to recongure your system using
the BIOS Setup program so that the computer can recognize these changes and record them
in the CMOS RAM of the SPI chip.
The SPI chip on the motherboard stores the Setup utility. When you start up the computer,
the system provides you with the opportunity to run this program. Press <Del> during the
Power-On Self-Test (POST) to enter the Setup utility; otherwise, POST continues with its test
routines.
Entering BIOS Setup at startup
To enter BIOS Setup at startup:
• Press <Delete> during the Power-On Self Test (POST). If you do not press <Delete>,
POST continues with its routines.
Entering BIOS Setup after POST
To enter BIOS Setup after POST:
• Press
<Ctrl>+<Alt>+<Del> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on. Do this option only if you
failed to enter BIOS Setup using the rst two options.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force
reset from a running operating system can cause damage to your data or system. We
recommend that you always shut down the system properly from the operating system.
• The default BIOS settings for this motherboard apply to most conditions to ensure
optimum performance. If the system becomes unstable after changing any BIOS
settings, load the default settings to ensure system compatibility and stability. Select the
Load Setup Defaults item under the Exit menu. See section 2.8 Exit Menu.
