Chapter 4. AMI BIOS SETUP

4.1 Introduction

AMI BIOS Setup program enables users to modify basic system configuration.
This special information is then stored in battery-backed RAM so that it retains
the Setup information when the power is turned off.

4.2 Starting Setup

AMI BIOS is immediately activated when you first turn on the computer. The
BIOS reads the system information contained in the CMOS and begins the
process of checking out the system and configuring it. When the process is
completed, the BIOS will seek an operating system on one of the disks, launch it
then turn control over to that operating system.

While the BIOS is in control, the Setup program can be activated in one of two
ways:

1. By pressing <Del> immediately after switching the system on, or

2. By pressing <Del> when the following message appears briefly at the bottom
of the screen during the POST.

Press DEL to enter SETUP

If the message disappears before you respond and you still wish to enter Setup,
restart the system by turning the power off momentarily or by pressing the
"RESET" button on the system case. You may also restart the system by
simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press
the keys at the right timing and the system does not boot, an error message will
be displayed and you will prompt to...

PRESS F2 to continue, DEL to enter SETUP

26

4.3 Using Setup

In general, you use the arrow keys to highlight items, press <Enter> to select,
use the PageUp and PageDown keys to change entries, press <F1> for help and
press <Esc> to quit. The following table provides additional details on how to
navigate in the Setup program using the keyboard.

F10 key Save all the CMOS changes, only for Main Menu

4.4 Getting Help

Press F1, a help window will pop up and describe the appropriate keys to use and
the possible selections for the highlighted item. To exit the Help Window, press
<Esc> or F1 again.

If you discover that your computer cannot boot after making and saving system
changes in the Setup Menu, AMI BIOS supports an override to the CMOS settings
that consequently resets your system to its default setting.
We strongly recommend you to avoid making any changes to the chipset defaults.
These defaults have been carefully chosen by both AMI and your systems
manufacturer to ensure a reliable performance.

27

4.5 Main Menu

Once you enter the AMIBIOS™ CMOS Setup Utility, the Main Menu will appear on
the screen. The Main Menu enables you to select from several setup functions
and two exit choices. Use the arrow keys to select among the items and press
<Enter> to accept and enter the sub-menu.

4.12 Hardware Monitor Setup

4.13 Change Supervisor Password

You can set either supervisor or user password, or both of them. The differences
between are:

Supervisor Password:

You can both access the Setup Menu as well as make changes in setting.

User Password:

You can only access but do not have the right to change the settings of BIOS
setup menus. When you select this function, the following message will appear
at the center of the screen prompt you to create a password.

ENTER PASSWORD:

Type the password of up to eight characters in length and press <Enter>. Any
previously entered password will be cleared from CMOS memory. When you are
asked to confirm the password, enter the password again and press <Enter>.
You may also press <Esc> to abort the selection.
To disable a password, press <Enter> when you are prompted to enter the
password. A message will pop up and ask you to confirm the selection. Once the
password is disabled, the system will boot and you can enter Setup freely.

PASSWORD DISABLED:

When a password has been enabled, you will be prompted to enter it every time
you try to enter Setup. This prevents any unauthorized party from changing your
system configuration.
Additionally, when a password is enabled, you can also require the BIOS to
request a password every time your system is rebooted. This would prevent
unauthorized use of your computer.

41

You can also determine when a password is required within the BIOS Features
Setup Menu and its Security option. If the Security option is set to “Always”,
password will be required both at boot and at entry to Setup. If the option is set
to “Setup”, password will only be prompted when trying to enter Setup.

42

Appendix A: Watchdog Timer

The Watchdog Timer is provided to ensure that standalone systems can always
recover from catastrophic conditions that cause the CPU to crash. This condition
may have occurred by external EMI or a software bug. When the CPU stops
working correctly, hardware on the board will either perform a hardware reset
(cold boot) or a Non-Maskable Interrupt (NMI) to bring the system back to a
known state.

A BIOS function call (INT 15H) is used to control the Watchdog Timer:

INT 15H:

AH – 6FH

Sub-function:

AL – 2: Set the Watchdog Timer’s period
BL: Time-out value (Its unit--second or minute, is

dependent on the item “Watchdog Timer unit select”
in CMOS setup).

You have to call sub-function 2 to set the time-out period of Watchdog Timer first.
If the time-out value is not zero, the Watchdog Timer will start counting down.
While the timer value reaches zero, the system will reset. To ensure that this
reset condition does not occur, please make sure that the Watchdog Timer is
being periodically refreshed by calling sub-function 2. However the Watchdog
timer will be disabled if you set the time-out value to zero.

A tolerance of at least 10% must be maintained to avoid unknown routines within
the operating system (DOS), such as disk I/O that can be very time-consuming.

Note: When exiting a program it is necessary to disable the Watchdog Timer,

otherwise the system will reset.

Example program:

; INITIAL TIMER PERIOD COUNTER
;

W_LOOP:

MOV AX, 6F02H ;setting the time-out value
MOV BL, 30 ;time-out value is 48 seconds

INT 15H

Appendix C: ATX Power Supply

The following notes show you how to connect ATX Power Supply.

For backplanes with ATX Connector

1. Disconnect the AC cord of the Power Supply from the AC source to prevent
sudden electric surge to the board.

2. Check the type of your Power Supply and find out +5VSB,PS-ON & GND.

 NOVA-8890 (through Power Button & GND):

Connect the ATX power button switch to the CN7 (power button). Then connect
the power cable from power supply. To turn ON the system, press the button
once. To turn off the power supply, hold down the ATX power switch button for
about 4 seconds.

46

Appendix D: How to use Wake-Up Function

NOVA-8890 provides two kinds of Wake up Function.
This page describes how to use Modem Wake-Up and LAN Wake-Up function.
Wake-Up function is enabled when you use ATX power supply.

Wake–Up On Modem (Ring):

You must set the option Resume on Ring of CMOS SETUP to enable this option.
The ATX power supply will be switched on when there is a ring signal detected on
pin “RI” of serial port.

Wake-Up On LAN:

You must set the option Resume on Ring (LAN2) & Resume on LAN (LAN1) of
CMOS SETUP to enable this option.

When your computer is turned off while LAN Link/Active LED is flashing, it
indicates that LAN chip has entered standby mode and waits for Wake-Up signal.
You can use other computers to wake up your computer by sending ID to it.

ID: ID is the MAC address of your system LAN. Every LAN chip has a factory-set
ID, which can be found from network information in WINDOWS.

ID’s format is xxxxxxxxxxxx
Example ID: 009027388320

47

Appendix E: Connecting LCD to NOVA-8890

NOVA-8890 can support both one-channel and two-channel LVDS LCD through
connector J3. We use the LCD–LTM15C423S (two-channel) for an example to
explain the signal mapping and data format.

The pixel data of LTM15C423S is 48-bit wide. To use 36-bit LCD, please neglect
the third pair of signals–(DATA3+, DATA3-). In other words, only the data of
MSB (R2 ~ R7, G2 ~ G7, B2 ~ B7) are left. On the other hand, if the one­channel LCD is used, only the first channel (CH1) is necessary. The way to deal
with 18-bit data is the same as that of 36-. For different types of LCD, you
should refer to the data sheet for more detailed information to make the right
connection.
