BIOS Introduction

This Chapter discusses Award™ Setup program built into the M4
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.

The AwardBIOS™ installed in M4 is a custom versio n of an industry
standard BIOS. This means that it supports VIA C7/EDEN in a
standard IBM-AT compatible input/output system. The BIOS provides
critical low-level support for standard devices such as disk drives and
serial and parallel ports.

It also adds non-standard, features such as virus and password
protection as well as special support for detailed fine-tuning of the
chipset controlling the entire system.

The rest of this chapter is intended to guide you through the process of
configuring your system using Setup.

Starting Setup

The AwardBIOS™ is immediatel y activated when you fir st power on
the computer. The BIOS reads the system i nform ation 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:

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 (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

36 EMB-M4 User`s Manual

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

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.

To display a sub menu

Use the arrow keys to move the cursor to the sub menu you want. Then
press <Enter>. A “¾” pointer marks all sub menus.

EMB-M4 User`s Manual 37

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.

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 AwardBIOS™
supports an override to the CMOS settings which resets your system to
its defaults.

The best advice is to only alter settings that 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 Award and M4 manufacturer to provide the absolute
maximum performance and reliability. Even a seemingly small
change to the chipset setup has th e poten tial for causing you to use the
override.

38 EMB-M4 User`s Manual

Main Menu

Once you enter the AwardBIOS™ 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 items and press <Enter> to accept and enter the
sub-menu.

This section allows you to configur e the system based on the specific
features of the installed chipset. This chipset manages bus speeds and
access to system memory resources, such as DRAM and the external
cache. It also coordinates communications between the conventional
ISA bus and the PCI bus. It must be stated that these items should never
need to be altered. The default settings have been chosen because they
provide the best operating conditions for your system. The only time
you might consider making any changes would be if you discovered
that data was being lost while using your system.

DRAM Settings

The first chipset settings deal with CPU access to dynamic random
access memory (DRAM). The default timings have been carefully
chosen and should only be altered if data is being lost. Such a scenario
might well occur if your system had mixed speed DRAM chips
installed so that greater delays may be required to preserve the integrity
of the data held in the slower memory chips.

Supervisor/User Password Setting

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

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

user password : just can only enter but do not have the right to
change the options of the setup menus. When you select this function,
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 enter ed password
from CMOS memory. You will be asked to confirm the password.
Type the password again and press <Enter>. You may also press
<Esc> to abort the selection and not enter a password.

To disable a password, just press <Enter> when you are prompted to
enter the password. A message will confirm the password 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 person
from changing any part of 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.

You determine when the password is required within the BIOS
Features Setup Menu and its Security option. If the Security option is
set to “System”, the password will be required both at boot and at entry
to Setup. If set to “Setup”, prompt ing only oc cur s when trying to enter
Setup.

Exit Selecting

Save & Exit Setup

Pressing <Enter> on this item asks for confirmation:

Save to CMOS and EXIT (Y/N)? Y

Pressing “Y” stores the selections made in the menus in CMOS – a
special section of memory that stays on after you turn your system off.
The next time you boot your computer, the BIOS configures your
system according to the Setup selections stored in CMOS. After saving
the values the system is restarted again.

Exit Without Saving

Pressing <Enter> on this item asks for confirmation:

Quit without saving (Y/N)? N

This allows you to exit Setup without storing in CMOS any change.
The previous selections remain in effect. This exits the Setup utility
and restarts your computer.

C. POST Beep

Currently there are two kinds of beep codes in BIOS. This code
indicates that a video error has occurred and the BIOS cannot initialize
the video screen to display any additional information. This beep code
consists of a single long beep followed by two short beeps.

The other code indicates that your DRAM error has occurred. This
beep code consists of a single long beep repeatedly.
