The BIOS provides critical low-level support for a standard device such as disk drives, serial ports and parallel ports. It also adds virus and password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system. BIOS Setup The Award BIOS provides a Setup utility program for specifying the system configurations and settings. The BIOS ROM of the system stores the Setup utility. When you turn on the computer, the Award BIOS is immediately activated. Pressing the key immediately allows you to enter the Setup utility. If you are a little bit late pressing the key, POST (Power On Self Test) will continue with its test routines, thus preventing you from invoking the Setup. If you still wish to enter Setup, restart the system by pressing the ”Reset” button or simultaneously pressing the , and keys. You can also restart by turning the system Off and back On again. The following message will appear on the screen: Press to Enter Setup In general, you press the arrow keys to highlight items, to select, the and keys to change entries, for help and to quit. When you enter the Setup utility, the Main Menu screen will appear on the screen. The Main Menu allows you to select from various setup functions and exit choices. 32 MB885 User’s Manual BIOS SETUP Phoenix - AwardBIOS CMOS Setup Utility Standard CMOS Features Frequency/Voltage Control Advanced BIOS Features Load Fail-Safe Defaults Advanced Chipset Features Load Optimized Defaults Integrated Peripherals Set Supervisor Password Power Management Setup Set User Password PnP/PCI Configurations Save & Exit Setup PC Health Status Exit Without Saving ESC : Quit Ç È Æ Å : Select Item F10 : Save & Exit Setup Time, Date, Hard Disk Type… The section below the setup items of the Main Menu displays the control keys for this menu. At the bottom of the Main Menu just below the control keys section, there is another section, which displays information on the currently highlighted item in the list. Note: If the system cannot boot after making and saving system changes with Setup, the Award BIOS supports an override to the CMOS settings that resets your system to its default. Warning: It is strongly recommended that you avoid making any changes to the chipset defaults. These defaults have been carefully chosen by both Award and your system manufacturer to provide the absolute maximum performance and reliability. Changing the defaults could cause the system to become unstable and crash in some cases. MB885 User’s Manual 33 BIOS SETUP Standard CMOS Setup “Standard CMOS Setup” choice allows you to record some basic hardware configurations in your computer system and set the system clock and error handling. If the board is already installed in a working system, you will not need to select this option. You will need to run the Standard CMOS option, however, if you change your system hardware configurations, the onboard battery fails, or the configuration stored in the CMOS memory was lost or damaged.
