Chapter 2 System Utilities The manufacturer or the dealer already configures most systems. There is no need to run Setup when starting the computer unless you get a Run Setup message. The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM. NOTE: If you repeatedly receive Run Setup messages, the battery may be bad/flat. In this case, the system cannot retain configuration values in CMOS.
Entering Setup Power on the computer and the system will start POST (Power On Self Test) process. When the message of “Press DEL to enter SETUP” appears on the screen, press the key of [Delete] to enter the setup menu. NOTE: If the message disappears before you respond and you still wish to enter Setup, restart the system by turning it OFF and On. You may also restart the system by simultaneously pressing [Ctrl+ Alt+ Delete].
The items in the main menu are explained below: Parameter Description Production Information This page shows the relevant information of the main board Standard CMOS Features This setup page includes all the items in standard compatible BIOS Advance BIOS Features This setup page includes all the items of Award special enhanced features Advance Chipset Features This setup page includes all advanced chipset features Integrated Peripherals This setup page includes all onboard peripherals Power Mana
Product Information The screen below appears if you select Product Information from the main menu: The Product Information menu contains general data about the system, such as the product name, serial number, BIOS version, etc. This information is necessary for troubleshooting (maybe required when asking for technical support).
