The Setup program allows users to modify the basic system configuration and save these settings to CMOS RAM. T he power of CMOS RAM is supplied by a battery so that it retains the Setup information when the power is turned off. Basic Input-Output System (BIOS) determines what a computer can do without accessing programs from a disk. T his system controls most of the input and output devices such as keyboard, mouse, serial ports and disk drives. BIOS activates at the first stag e o f the booting process, loading and executing the operating system. Some additional features, such as virus and password prot ection or chipset fine-tuning options are also included in BIOS. T he rest of this manual will to guide you through the options and settings in BIOS Setup. Plug and Pla y Support T his AMI BIOS supports the Plug and Play Version 1.0A specification. EPA Green PC Support T his AMI BIOS supports Version 1.03 of the EPA Green PC specification. ACPI Support AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power interface specifi cation (ACPI). It provides ASL code for pow er manag ement and device con figuration capabilities as defined in the ACPI specification, developed by Microso ft, Intel and T oshiba. 1 H55 HD BIOS Manual PCI Bus Support T his AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component Interconn ect) local bus speci fication. DRAM S upport DDR3 SDRAM (Double Data Rate III Synchronous DRAM) is supported. Supported CP Us T his AMI BIOS supports the Intel CPU. Using Setup When starting up the computer, press <Del> during the Power-On Self-Test (POST) to enter the BIOS setup utility. In the BIOS setup utility, you will see General Help description at the top right corner, and this is providing a brief description of the selected item. Navigation Keys for that particular menu are at the bottom right corner, and you can use these keys to select item and ch ange the settings. General Help Navigation Keys Notice z z z T he default BIOS settings apply for most conditions to ensure optimum performan ce of the motherboard. If the system becomes unstable after changing any settings, please load the default settings to ensure system’s compatibility and stability. Use Load Setup Default under the Exit Menu. For better system perform ance, the BIOS firmware is being continuously updated. T he BIOS information described in this manual is for your reference only. T he actual BIOS information and settings on board may be slightly different from this manual. T he content of this manual is subject to be chang ed without notice. We will not be responsible for any mistakes found in this user’s manual and any system damage that may be caused by wrong-settings. 2 H55 HD BIOS Manual 1 Main Menu Once you enter AMI BIOS Setup Utility, the Main Menu will appear on the screen providing an overview of the basic system inform ation.
