AMI BIOS SETUP

4.1 Introduction

This chapter discusses AMI's Setup program built into the ROM BIOS.
The Setup program allows users to modify the 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

The AMI BIOS is immediately activated when you first boot up the
computer. The BIOS reads the system information contained in the
CMOS and begins the process of checking out the system and then
configures it. When it finishes, the BIOS will seek an operating system
on one of the disks and then launch and pass the control over to the
operating system.
While the BIOS is in charge, the Setup program can be activated in one
of the following ways:

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

2. by pressing the <Del>key 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, press the “RESET” button on the chassis or turn the power
off then turn it back on to restart the system then you can try again.
You may also restart by simultaneously pressing <Ctrl>, <Alt>, and
<Delete> keys. If you do not press the keys at the correct moment and
the system does not boot, an error message will be displayed and you
will again be asked to...

PRESS F2 TO CONTINUE, DEL TO ENTER SETUP

30

4.3 Using Setup

In general, you use the arrow keys to highlight options, 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
more detail about how to navigate in the Setup program using the
keyboard.

Up arrow Move to previous option
Down arrow Move to next option
Left arrow Move to the option in the left column
Right arrow Move to the option in the right column
Esc key Main Menu -- Quit and not save changes into CMOS

Status Page Setup Menu and Option Page Setup

Menu -- Exit current page and return to Main Menu
PgUp key Increase the numeric value or make changes
PgDn key Decrease the numeric value or make changes
+ key Increase the numeric value or make changes

- key Decrease the numeric value or make changes
F1 key General help, only for Status Page Setup Menu and

Option Page Setup Menu
F2 /F3 key Change color from total 16 colors. F2 to select color

forward, (Shift) F2 to select color backward
F4 key Reserved
F5 key Reserved
F6 key Reserved
F7 key Reserved
F8 key Reserved
F9 key Reserved
F10 key Save all the CMOS changes, only for Main Menu

31

4.4 Getting Help

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

If, after making and saving system changes with Setup, you discover
that your computer is no longer able to boot, the AMI BIOS supports an
override to the CMOS settings which can reset your system to its
defaults.

The best advice is to alter only the settings which you thoroughly
understand. To this end, we strongly recommend not to make any
changes to the chipset defaults. These defaults have been carefully
chosen by both AMI and the system manufacturer to provide the
optimum performance and reliability. Even a seemingly little change to
the chipset setup may shut the system down and need the override
program to reset it.

32

4.5 Main Menu

Once you enter the AMIBIOS™ CMOS Setup Utility, the Main Menu will
appear on the screen. The Main Menu allows you to select from several
setup functions and two exit choices. Use the arrow keys to select
among

the option and press <Enter> to accept and enter the sub-menu.
Note that a brief description of each highlighted selection appears at the
bottom of the screen.
The main menu includes the following main setup categories. Recall that
some systems may not include all entries.

Standard CMOS Setup

Use this menu for basic system configuration.

Advanced CMOS Setup

Use this menu to set the Advanced Features available on your system.

Advanced Chipset Setup

33

Use this menu to change the values in the chipset registers and optimize
the system's performance.

Power Management Setup

When Disabled, SMI will not be initialized, and complete power
management functionality is removed unless this option is set to Enabled.

PCI / Plug and Play Setup

This entry appears if your system supports PnP / PCI.

Peripheral Setup

Use this menu to specify your settings for integrated peripherals.

Hardware Monitor Setup

Use this menu to monitor your hardware.

Auto-detect Hard Disks

Use this menu to specify your settings for hard disks control.

Change Supervisor Password

Use this menu to set User and Supervisor Passwords.

Auto Configuration with Optimal Settings

Use this menu to load the BIOS factory settings for optimal system
performance. While AMI has been designed the custom BIOS to
optimize performance, the factory has the right to change these defaults
to meet its needs.

34

Auto Configuration with Fail-Safe Settings

Use this menu to load the BIOS default values for the safe and stable
system performance.

Save Settings and Exit

Save CMOS value changes to CMOS and exit setup.

Exit Without Saving

Abandon all CMOS value changes and exit setup.

4.6 Standard CMOS Setup

The options in Standard CMOS Setup Menu are divided into 10
categories. Each category includes none, one or more than one setup
options. Use the arrow keys to highlight the option and then use the
<PgUp> or <PgDn> keys to select the value you want for each
option.

Enhanced Parallel Port(EPP) specification. EPP uses the
existing parallel port signals to provide asymmetric
bidirectional data transfer driven by the host device.

ECP: The parallel port can be used with devices that adhere to the

Entended Capabilities Port(ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5
Megabits persecond. ECP provides symmetric bidirectional
communication.

4.13 Change Supervisor Password

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

supervisor password:
can enter and change the settings of the setup menus.

user password:
can only access the setup menus, but can’t change anything of it. When
you select this option, the following message will appear at the center
of the screen to assist you in creating a password.

ENTER PASSWORD:
Type the password, up to eight characters in length, and press <Enter>.
The password typed now will clear any previously existing password
within CMOS memory. You will be prompted to confirm the password.
Type the password again and press <Enter>. You may also press
<Esc> to abort the selection and not to enter a password.
To disable a password, just press <Enter> when you are prompted to
enter the password. A message which ask you to confirm the password

52

will be disabled. 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 an unauthorized user
from changing any bit of your system configuration.
Additionally, when a password is enabled, you can also require the
BIOS to request a password every time the system is booting. This
would prevent unauthorized uses of your computer.
The user can determine whether the password is needed for entering
BIOS Setup Program or other Security options (see Section 4.5). Once
the Password has been set, The user will be prompted to enter the
password at the beginning of booting and at the entry to Setup Menu.

This chapter discusses the Setup program built into the BIOS; it allows
users to configure the system. This configuration is then stored in
battery-backed CMOS RAM so that Setup information is retained whilst
the power is off.

53

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(the time unit--second or minute, is
dependent on the item “Watchdog Timer unit

selected in BIOS 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. When the timer value
reaches zero, the system will reset. To ensure that this reset
condition does not occur, the Watchdog Timer must be
periodically refreshed by calling sub-function 2. However the
Watchdog timer will be disabled if you set the time-out value to
be 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.

54

Note: when exiting a program it is necessary to disable the

Watchdog Timer, otherwise the system will reset.

Example program:

Appendix C.

How to use the Wake-Up Function

The WAFER-E668EV provides two kind of Wake Up Function.
This page describes how to use the Modem Wake-Up and LAN Wake­Up functions.
Wake-Up function works whilst using ATX power supply,

Wake-Up By Modem Ring On:
In CMOS SETUP, the user must set the option Wake Up On
LAN/Ring to enabled. The ATX power supply will be switched on when
there is a ring signal detected on the pin “RI” of the serial port.

Wake-Up On LAN:
In CMOS SETUP, the user must set the option Wake Up On
LAN/Ring to enabled. When the computer is in power-down status, a
LAN Link/Active LED is flashing. This status indicates that the LAN chip
has entered standby mode and is waiting for a Wake-Up signal. You can
use other computers to wake up your computer by sending ID to it.

ID: ID is the address of your system LAN. Every LAN chip has a factory-

set ID which you can find it from network information in WINDOWS.

ID’s format is xx- xx- xx- xx- xx-xx
Example ID: 00905C21D4

58

Appendix D. Digital I/O

One characteristic of digital circuit is its fast response to high or low
signal. This kind of response is highly needed for harsh and critical
industrial operating environment. That’s why we design 4-bit digital
inputs and 4-bit digital outputs on the WAFER-E668EV.
There are two kinds of signals (Input and Output) used by the Digital
I/O function. These signals are used to control external devices that
need On/Off circuit or TTL devices. When one of the signals has
been selected, The user can read or write data to the system
through the Digital I/O function.

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

INT 15H :

AH – 6FH

Sub-function:

AL – 8 : Set the Digital port as INPUT
AL : Digital I/O input value

Example program:

MOV AX, 6F08H ;setting the Digital port i s i nput
INT 15H ;

AL low byte = value

AH – 6FH

Sub-function:

AL – 9 : Set the Digital port as OUTPUT
BL : Digital I/O output value

59

Example program:

MOV AX, 6F09H ;setting the Digital port i s output
MOV BL, 09H ;Digital value is 09H
INT 15H ;

Digital Output is 1001b
