BIOS setup program
This motherboard supports a programmable firmware 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, reconfiguring your
system, or prompted to “Run Setup”. This section explains how to configure your system
using this utility.
Even if you are not prompted to use the Setup program, you can change the configuration 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 reconfigure your system using
the BIOS Setup program so that the computer can recognize these changes and record them
in the CMOS RAM of the firmware chip.
The firmware 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.
If you wish to enter Setup after POST, reboot the system by doing any of the following
procedures:
• Restart using the OS standard shut-down procedure.
• 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.
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 to
always shut-down the system properly from the operating system.
The Setup program is designed to make it as easy to use as possible. Being a menu-driven
program, it lets you scroll through the various submenus and make your selections from the
available options using the navigation keys.
• The default BIOS settings for this motherboard apply for 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 Setups Default
item under the Exit Menu. See section
2.9 Exit Menu
.
