1. Getting Started

1.1 Safety Precautions

Warning!

Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should
open the PC chassis.

Caution!

Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution,
use a grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded
bag when they are not in the chassis.

Always note that improper disassembling action could cause damage to the

motherboard. We suggest not removing the heatsink without correct
instructions in any circumstance. If you really have to do this, please contact
us for further support.

You can configure your board to match the needs of your application by setting jumpers. A

jumper is the simplest kind of electric switch.

It consists of two metal pins and a small metal clip (often protected by a plastic cover) that

slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.

To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1,

2, and 3. In this case, you would connect either two pins.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
If you have any doubts about the best hardware configuration for your application, contact
your local distributor or sales representative before you make any changes.

The following tables list the function of each of the board’s jumpers and connectors.

3.1 Introduction

The BIOS setup program allows users to modify the basic system configuration. In this
following chapter will describe how to access the BIOS setup program and the
configuration options that may be changed.

3.2 Starting Setup

The AMI BIOS™ is immediately activated when you first power 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 it finishes, the BIOS will seek an operating system
on one of the disks and then launch and turn control over to the operating system.

While the BIOS is in control, the Setup program can be activated in one of two ways:
By pressing <Del> immediately after switching the system on, or
By pressing the <Del> key when the following message appears briefly at the bottom of the
screen during the POST (Power On Self Test).

Press DEL to enter SETUP

If the message disappears before you respond and you still wish to enter Setup, restart the
system to try again by turning it OFF then ON or pressing the "RESET" button on the
system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete>
keys. If you do not press the keys at the correct time and the system does not boot, an error
message will be displayed and you will again be asked to.

Press F1 to Continue, DEL to enter SETUP

3.3 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 more detail about how to navigate in the Setup program
using the keyboard.

 Navigating Through The Menu Bar

Use the left and right arrow keys to choose the menu you want to be in.

Note: Some of the navigation keys differ from one screen to another.

 To Display a Sub Menu

Use the arrow keys to move the cursor to the sub menu you want. Then press
<Enter>. A “” pointer marks all sub menus.

3.4 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.

3.5 In Case of Problems

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

The best advice is to only alter settings which you thoroughly understand. To this end, we
strongly recommend that you avoid making any changes to the chipset defaults. These
defaults have been carefully chosen by both AMI and your systems manufacturer to
provide the absolute maximum performance and reliability. Even a seemingly small change
to the chipset setup has the potential for causing you to use the override.

EMX-CDV User’s Manual

3.6 BIOS setup

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

3.6.1 Main Menu

This section allows you to record some basic hardware configurations in your computer and
set the system clock.

3.6.1.1 System Date

Use the system Date option to set the system date. Manually enter the day, month and
year.

3.6.1.2 System Time

Use the system time option to set the system time. Manually enter the hours, minutes and
seconds.

Note: BIOS setup screens shown in this chapter are for reference only, and may

not exactly match what you see on your screen. Visit the Avalue website
(www.avalue.com.tw) to download the latest product and BIOS information.

This setting specifies a password that must be entered to access the BIOS Setup Utility. If
only the Administrator's password is set, then this only limits access to the BIOS setup
program and is only asked for when entering the BIOS setup program. By default, no
password is specified.

3.6.5.2 User Password

This setting specifies a password that must be entered to access the BIOS Setup Utility or
to boot the system. If only the User's password is set, then this is a power on password and
must be entered to boot or enter the BIOS setup program. In the BIOS setup program, the
User will have Administrator rights. By default, no password is specified.
