BIOS Setup 2
AMI®BIOS Setup
The mainboard uses AMI®BIOS ROM that provides a Setup utility for
users to modify the basic system configuration. The information is stored in a
battery-backed CMOS RAM so it retains the Setup information when the power
is turned off.
The chapter contains the following topics:
Entering Setup 2-2
Selecting the First Boot Device 2-2
Control Keys 2-3
Getting Help 2-3

Entering Setup
Power on the computer and the system will start POST (Power On
Self Test) process. When the message below appears on the screen, press
<DEL> key to enter Setup.
DEL:Setup F11:Boot Menu F12:Network boot TAB:Logo
If the message disappears before you respond and you still wish to
enter Setup, restart the system by turning it OFF and On or pressing the
RESET button. You may also restart the system by simultaneously pressing
<Ctrl>, <Alt>, and <Delete> keys.
Selecting the First Boot Device
Select First Boot Device
Floppy : 1st Floppy
IDE-0 : IBM-DTLA-307038
CDROM : ATAPI CD-ROM DRIVE 40X M
[Up/Dn] Select [RETURN] Boot [ESC] cancel
You are allowed to select the 1st boot device without entering the BIOS setup
utility by pressing <F11>. When the same message as listed above appears on
the screen, press <F11> to trigger the boot menu.
The POST messages might pass by too quickly for you to respond in
time. If so, restart the system and press <F11> after around 2 or 3 seconds
to activate the boot menu similar to the following.
The boot menu will list all the bootable devices. Select the one you
want to boot from by using arrow keys and then pressing <Enter>. The
system will boot from the selected device. The selection will not make
changes to the settings in the BIOS setup utility, so next time when you
power on the system, it will still use the original first boot device to boot up.

Getting Help
After entering the Setup utility, the first screen you see is the Main Menu.
MainMenu
The main menu displays the setup categories the BIOS supplies. You can use
the arrow keys ( ↑↓ ) to select the item. The on-line description for the selected
setup category is displayed on the bottom of the screen.
Default Settings
The BIOS setup program contains two kinds of default settings: the BIOS
Setup and High Performance defaults. BIOS Setup defaults provide stable
performance settings for all devices and the system, while High Performance
defaults provide the best system performance but may affect the system
stability.
Control Keys
<↑> Move to the previous item
<↓> Move to the next item
<←> Move to the item in the left hand
<→> Move to the item in the right hand
<Enter> Select the item
<Esc> Jumps to the Exit menu or returns to the main menu from a submenu
<+/PU> Increase the numeric value or make changes
<-/PD> Decrease the numeric value or make changes
<F5> Restore the previous CMOS value from CMOS, only for Option Page
Setup Menu
<F6> Load High Performance defaults, only for Option Page Setup Menu
<F7> Load BIOS Setup defaults
<F10> Save all the CMOS changes and exit

The Main Menu
Once you enter AMIBIOS SIMPLE SETUP UTILITY, the Main Menu will
appear on the screen. The Main Menu displays twelve configurable
functions and two exit choices. Use arrow keys to move among the items
and press <Enter> to enter the sub-menu.

Standard CMOS Features
The items inside STANDARD CMOS SETUP menu are divided into 9
categories. Each category includes none, one or more setup items. Use the
arrow keys to highlight the item you want to modify and use the <PgUp> or
<PgDn> keys to switch to the value you prefer.
