BIOS Introduction
This Chapter discusses Award™ Setup program built into the M3
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 M3 SBC is a custom version of an
industry standard BIOS. This means that it supports Intel PentiumIV 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 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 Set up 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

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.

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 M2 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.

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.

Menu Level
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 be cause 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.
50 EMB-M3 User`s Manual
DRAM Timing Selectable
This item allows you to select the DRAM timing determined by the
timing information stored in SPD or set by the User manually. The
default is By SPD. Wh en this field is set as By SPD, the DRAM Timing
items below will become read-only.
The choice: By SPD, Manual.
CAS Latency Time
When synchronous DRAM is installed, the number of clock cycles of
CAS latency depends on the DRAM timing. Do not reset this field
from the default value specified by the system designer.
The choice: 3, 2.5, 2, 1.5.
Active to Precharge Delay
This item allows you to set the Active to Precharge D elay of DRAM
timing. Do not reset this field from the default value specified by the
system designer.
The choice: 5.
DRAM RAS# to CAS# Delay
When DRAM is refreshed, both rows and columns are addressed
separately. This field allows you to determine the timing of transition
from Row Address Strobe (RAS) to Column Address Strobe (CAS).
The choice: 3, 2.
DRAM RAS# Precharge
The precharge time is the number of cycles it takes for the RAS to
accumulate its charge before DRAM refresh. If insufficient time is
allowed, refresh may be inco mplete and the DRAM may fail to retain
data.
The choice: 3, 2.

In order to improve performance, certain space in memory can be

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