A S U S P 5 G C - M X 2 - 1 1 2.2 BIOS setup program This motherboard supports a programmable rmware 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 rmware hub. The rmware hub 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, restart the system by pressing <Ctrl Alt Delete>, or by pressing the reset button on the system chassis. You can also restart by turning the system off and then back on. Do this last option only if the rst two failed. 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 sub-menus 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 Default Settings item under the Exit Menu. See section “2.7 Exit Menu.” • The BIOS setup screens shown in this section are for reference purposes only, and may not exactly match what you see on your screen. • Visit the ASUS website (www.asus.com) to download the latest BIOS le for this motherboard.
