Chapter 5 BIOS Setup
The BIOS setup Utility record settings and information of your computer,
such as date and time, the type of hardware installed, and various configuration
settings. Your computer applies those information to initialize all the
components when booting up and basic function of coordination between system
components.
If the Setup Utility configuration is incorrect, it may cause the system to
malfunction. It can even stop you computer booting properly. If it happens, you
can use the clear CMOS jumper to clear the CMOS memory which has stored
the configuration information; or you can hold down the Page
Up Key while rebooting your computer. Holding down the Page Up key also
clears the setup information.

5.1 Main menu
You can use cursor arrow keys to highlight anyone of options on the main menu
page. Press Enter to select the highlighted option. Press the Escape key to leave
the setup utility. Press the F9 key to go back to menu in BIOS. Some options on
the main menu page lead to tables of items with installed value that you can use
cursor arrow keys to highlight on item, and press page
Up and page Down keys to cycle through alternative values of that item. The
other options on the main menu page lead to dialog boxes that require your
answer Yes or No by hitting the Y or N keys. If you have already changed the
setup utility, press F10 to save those changes and exit the utility.
