Jumper Setting
EBC573 User’s Manual 14 Chapter 2
This chapter of the User’s Manual describes how to set jumpers.
Note: The procedures that follow are generic for all EBC573 series.
2.1 Before You Begin
Ensure you have a stable, clean working environment. Dust and dirt can get into components and cause a
malfunction. Use containers to keep small components separated.
Adequate lighting and proper tools can prevent you from accidentally damaging the internal components.
Most of the procedures that follow require only a few simple tools, including the following:
♦ A Philips screwdriver
♦ A flat-tipped screwdriver
♦ A set of jewelers Screwdrivers
♦ A grounding strap
♦ An anti-static pad
Using your fingers can disconnect most of the connections. It is recommended that you do not use
needle-nosed pliers to disconnect connections as these can damage the soft metal or plastic parts of the
connectors.
Before working on internal components, make sure that the power is off. Ground yourself before touching
any internal components, by touching a metal object. Static electricity can damage many of the electronic
components. Humid environment tend to have less static electricity than dry environments. A grounding
strap is warranted whenever danger of static electricity exists.
2.2 Precautions
Computer components and electronic circuit boards can be damaged by discharges of static electricity.
Working on the computers that are still connected to a power supply can be extremely dangerous. Follow
the guidelines below to avoid damage to your computer or yourself:
♦ Always disconnect the unit from the power outlet whenever you are working inside the case.
♦ If possible, wear a grounded wrist strap when you are working inside the computer case. Alternatively,
discharge any static electricity by touching the bare metal chassis of the unit case, or the bare metal
body of any other grounded appliance.
♦ Hold electronic circuit boards (such as the EBC573 board) by the edges only. Do not touch the
components on the board unless it is necessary to do so. Don’t flex or stress the circuit board.
♦ Leave all components inside the static-proof packaging that they shipped with until they are ready for
installation.
♦ Use correct screws and do not over tighten screws.
EBC573 User’s Manual 15 Chapter 2
2.3 Setting Jumpers
A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. When setting the
jumpers, ensure that the jumper caps are placed on the correct pins. When the jumper cap is placed on
both pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin,
the jumper is OPEN. Please see the following illustrations
The illustrations on the right show
a 2-pin jumper. When the jumper
cap is placed on both pins, the
jumper is SHORT. If you remove
the jumper cap, or place the
jumper cap on just one pin, the
jumper is OPEN.
These illustrations show a 3-pin
jumper. Pins 1 and 2 are SHORT.

Award BIOS Setup
EBC573 User’s Manual 44 Appendix A
This chapter explains how to use the BIOS Setup program for the EBC573. The current BIOS setup pictures
in the chapter are for reference only, which may change by the BIOS modification in the future. User can
download any major updated items or reversion from NEXCOM web site http://www.nexcom.com.tw. If any
unclear message occurs, please contact NEXCOM customer service representative for help or log onto
http://www.nexcom.com.tw/contact/contact.htm
.
4.1 About the BIOS
The BIOS (Basic Input and Output System) Setup program is a menu driven utility that enables you to
make changes to the system configuration and tailor your system to suit your individual work needs. It is
a ROM-based configuration utility that displays the system’s configuration status and provides you with a
tool to set system parameters. These parameters are stored in non-volatile battery-backed-up CMOS
RAM that saves this information even when the power is turned off. When the system is turned back on,
the system is configured with the values found in CMOS.
With easy-to-use pull down menus, you can configure such items as:
♦ Hard drives, diskette drives, and peripherals
♦ Video display type and display options
♦ Password protection from unauthorized use
♦ Power management features
The settings made in the Setup program intimately affect how the computer performs. It is important,
therefore, first to try to understand all the Setup options, and second, to make settings appropriate for the
way you use the computer.
4.2 When to Run BIOS
This program should be executed under the following conditions:
♦ When changing the system configuration
♦ When a configuration error is detected by the system and you are prompted to make changes to
the Setup program
♦ When resetting the system clock
♦ When redefining the communication ports to prevent any conflicts
♦ When making changes to the Power Management configuration
♦ When changing the password or making other changes to the security setup
Normally, CMOS setup is needed when the system hardware is not consistent with the information
contained in the CMOS RAM, whenever the CMOS RAM has lost power, or the system features need to
be changed.
EBC573 User’s Manual 45 Appendix A
4.3 Entering Setup
When the system is powered on, the BIOS will enter the Power-On Self Test (POST) routines. These
routines perform various diagnostic checks; if an error is encountered, the error will be reported in one of
two different ways:
♦ If the error occurs before the display device is initialized, a series of beeps will be transmitted.
♦ If the error occurs after the display device is initialized, the screen will display the error message.
Powering on the computer and immediately pressing <Del> allows you to enter Setup. Another way to
enter Setup is to power on the computer and wait for the following message during the POST:
TO ENTER SETUP BEFORE BOOT
PRESS <CTRL+ALT+DEL > KEY
Press the <Del> key or press the <Ctrl>, <Alt>, and <Esc> keys to enter Setup:
4.4 The Main Menu
Once you enter Award BIOS CMOS Setup Utility, the Main Menu (Figure 1) will appear on the screen.

4.8 Advanced BIOS Features
Selecting Advanced BIOS Feature on the main program screen displays this menu, which allows you to
define advanced information about your system. You can make modifications to most of these items to
improve your system performance or set up system features according to your preference, without causing
fatal errors to your system.
Figure 4-3: BIOS – Advanced BIOS Features
The following explains the options for each feature:
Virus Warning
Allow you to choose the Virus Warning feature for IDE Hard Disk boot sector protection. If this function
is enabled and someone attempts to write data into this area, BIOS will show a warning message on
screen and an alarm will beep.
♦ Enabled: Activates automatically when the system boots up causing the following warning
message to appear when anything attempts to access the boot sector or hard disk partition table:
!WARNING!
Disk boot sector is to be modified
Type “Y” to accept write or “N” to abort write
Award Software, Inc.
♦ Disabled: No warning message will appear when an attempt is made to access the boot sector or
hard disk partition table.
EBC573 User’s Manual 51 Appendix A
Note: This function is available only for DOS and other operating systems that do not trap INT13.
For complete protection against viruses, install virus software in your operating system and
update the virus definitions regularly.
Many disk diagnostic programs that access the boot sector table can trigger the virus warning
message. If you plan to run such a program, we recommend that you disable the virus
warning.
CPU L1, L2 and L3 Cache
Cache memory is an additional memory that is much faster than conventional DRAM (system memory).
This BIOS feature is used to enable or disable the processor's Level 1, Level 2 and Level 3 cache.
Naturally, the default and recommended setting is Enabled.
Note: This field will be available only if your CPU supports this function.
First/Second/Third Boot Device
BIOS attempts to load the operating system from the devices in the sequence selected. The available
choices are: Floppy, HDD-0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, USB-FDD, USBZIP,
USB-CDROM, USB-HDD, LAN, and Disabled.
Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key when the system boot. If On, the
numeric keypad is in numeric mode. If Off, the numeric keypad is in cursor control mode.
Gate A20 Option
Gate A20 refers to the way the system addresses memory above 1MB (extended memory). This feature
enables you to select whether the chipset or the keyboard controller should control Gate A20. The options
are:
♦ Normal: A pin in the keyboard controller controls Gate A20
♦ Fast : Let system chipsets control Gate A20. The fast setting improves system speed, particularly
with OS/2 and windows.
Security Option
Enables you to select whether the password is required every time the system boots or only when you
enter Setup.
♦ System: The system will not boot and access to Setup will be denied if the correct password is not
entered at the prompt.
♦ Setup: The system will boot, but access to Setup will be denied if the correct password is not entered
at setup.
EBC573 User’s Manual 52 Appendix A
4.9 Advanced Chipset Features
Since the features in this section are related to the chipset in the CPU board and all are optimized, you are
not recommended to change the default settings in the setup table, unless you understand the chipset
features.
This section allows you to configure the system based on the specific features of the installed chipset.
This chipset manage 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. 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.
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 has 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.
Selecting Advanced Chipset Features on the main program screen displays this menu:
Figure 4-4: BIOS – Advanced Chipset Features
System BIOS cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better
system performance. However, if any program writes to this memory area, a system error may result. The
available choices are Enabled, Disabled.
EBC573 User’s Manual 53 Appendix A
Video BIOS Cacheable
Selecting Enabled allows caching of the video BIOS ROM at C0000h, resulting in better video
performance. However, if any program writes to this memory area, a system error may result. The choices:
Enabled, Disabled.
On-Chip VGA
By default, the On-Chip VGA or chipset-integrated VGA is Enabled.
On-Chip Frame Buffer Size
The On-Chip Frame Buffer Size can be set as 1, 4, 8, 16 or 32MB. This memory is shared with the system
memory.
Boot Display
Boot Display determines the display output device where the system boots. The options are Auto, CRT,
LFP, and CRT+LFP.
Panel Type
This field allows user to decide the LVDS panel resolution. Please refer to the BIOS for the resolution.
After you have made your selections in the Advanced Chipset Features setup, press <ESC> to go back to
the main screen. The options are 640x480 18bits, 800x600 18bis, 1024x768 18bits.
TV Standard
This item allows you to designate the type of colored TV standard to be used when a TV receiver is
connecting to the TV out port. If a TV receiver is not connected to the XL2, this setting should be
disabled. NTSC is for U.S. colored TVs; PAL is for European and other non-U.S. TVs.

Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you
wish to use it. If you install an add-in FDC or the system has no floppy drive, select Disabled to this field.
Onboard Serial Ports (1, 2, 3, 4)
This feature allows you to manually select the I/O address and IRQ for the first and second serial ports. It
is recommended that you leave it as Auto so that the BIOS can select the best settings for it. But if you
need a particular I/O port or IRQ that's been taken up by this serial port, you can manually select an
alternative I/ O port or IRQ for it. You can also disable this serial port if you do not need to use it. Doing
so frees up the I/O port and IRQ used by this serial port. Those resources can then be reallocated for other
devices to use.
UART Mode Select
Select an operating mode for the serial port.
The choices are: Normal, IrDA, ASKIR.
UR2 Duplex Mode
In an infrared port mode, this field appears. Full-duplex mode permits simultaneous two-direction
transmission. Half-duplex mode permits transmission in one direction only at a time. Select the value
required by the IR device connected to the IR port.
Onboard Parallel Port
This feature allows you to select the I/O address and IRQ for the onboard parallel port. The default I/O
address of 378h and IRQ of 7 should work well in most cases. Unless you have a problem with the
parallel port, you should leave it at the default settings. The choices: 378/IRQ7, 278/IRQ5, 3BC/IRQ7,
and Disabled.
Parallel Port Mode
Select an operating mode for the onboard parallel (printer) port. There are four options: SPP (Standard
Parallel Port), EPP (Enhanced Parallel Port), ECP (Extended Capabilities Port) and ECP+EPP.
ECP Mode Use DMA
When the on-board parallel port is set to ECP mode, the parallel port can use DMA3 or DMA1.
Serial Port 3\4 Use IRQ
This assigns an IRQ to the serial port 3\4.
EBC573 User’s Manual 56 Appendix A
4.11 Power Management Setup
This option lets you control system power management. The system has various power-saving modes
including powering down the hard disk, turning off the video, suspending to RAM, and software power
down that allows the system to be automatically resumed by certain events.
The power-saving modes can be controlled by timeouts. If the system is inactive for a time, the timeouts
begin counting. If the inactivity continues so that the timeout period elapses, the system enters a power
saving mode. If any item in the list of Reload Global Timer Events is enabled, then any activity on that
item will reset the timeout counters to zero.
If the system is suspended or has been powered down by software, it can be resumed by a wake up call
that is generated by incoming traffic to a modem, a LAN card, a PCI card, or a fixed alarm on the system
realtime clock. Selecting Power Management Setup on the main program screen displays this menu:
Figure 4-6: BIOS – Power Management Setup
ACPI Function
The ACPI standard (Advanced Configuration and Interface power) allows the operating system directly to
check the functions of energy saving and the PnP (Plug and Play) functionality. The ACPI functions are
normally activated by the BIOS. The choices are: Enabled and Disabled.
EBC573 User’s Manual 57 Appendix A
Video Off Method
This determines the manner in which the monitor is blanked. There are three choices:
1. V/H SYNC+Blank: This selection will cause the system to turn off the vertical and horizontal
synchronization port and write blanks to the video buffer.
2. Blank Screen: This option only writes blanks to the video buffer.
3. DPMS Support: Select this option if your monitor supports the Display Power Management signaling
(DPMS) standard of the Video Electronics Standard to select video power management values.
Video Off In Suspend
This determines the manner in which the monitor is blanked. The choices: Yes, No.
Suspend Mode
After the selected period of system inactivity, all devices except the CPU shut off. The choices are 1~2
min, 2~3 min,…. Up to 1 hour.
HDD Power Down
After the selected period of drive inactivity, the hard disk drive powers down while all other devices
remain active.
Wake up by PCI Card
When the system enters a Soft-off mode (Standby power exists but system is not working), it will wake
up system when specific signals occurred. The BIOS monitors the system for “activity” to determine
when to enable power management.
If you enable this feature, the computer specifies that any signal noticed on the PCI (Peripheral
Component Interconnect) bus channel must make go out from the hibernation state. The choices: Enabled,
Disabled.

The events are I/O events whose occurrence can prevent the system from entering a power saving mode
or can awaken the system from such a mode. In effect, the system remains alert for anything, which
occurs to a device, which is configured as Enabled, even when the system is in a power down mode. The
choices are Enabled, and Disabled.
After you have made your selections in the Power Management setup, press the <ESC> key to go back to
the main program screen.

4.12 PnP/PCI Configurations
This section describes configuring the PCI bus system. Peripheral Component Interface, is a system
which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating
with its own special components. This section covers some very technical items and it is strongly
recommended that only experienced users should make any changes to the default settings.
Selecting PnP/PCI Configurations on the main program screen displays this menu:

Reset Configuration Data
Normally, you leave this field Disabled, Select Enabled to reset Extended System Configuration Data
(ESCD) when you exit Setup if you have installed a new add-on Card and the system reconfiguration has
caused such a serious conflict that the operating system can not boot. The choices are Enabled and
Disabled.
Resources Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all of the boot and Plug and
Play compatible devices. However, this capability means absolutely nothing unless you are using a Plug
and Play operating system such as going into each of the submenus that follows this field. The choices are
Auto (ESCD), Manual.

4.14 Load Fail-Safe Defaults
This option opens a dialog box that lets you install fail-safe defaults for all appropriate items in the whole
setup utility. Press the <Y> key and then <Enter> to install the defaults. Press the <N> key and then
<Enter> to not install the defaults.
Use this option if you have changed your system and it does not operate correctly or does not power up.
4.15 Load Optimized Defaults
This option opens a dialog box that lets you install optimized defaults for all appropriate items in the
whole setup utility. Press the <Y> key and then <Enter> to install the defaults. Press the <N> key and
then <Enter> to not install the defaults. The optimized defaults place demands on the system that may be
greater than the performance level of the components, such as the CPU and the memory. You can cause
fatal errors or instability if you install the optimized defaults when your hardware does not support them.
If you only want to install setup defaults for a specific option, select and display that option, and then
press the <F7> key.

4.16 Set Password
The User Password utility sets the password. The main board is shipped with the password disabled. If
you want to change the password, you must first enter the current password, then at the prompt enter your
new password. The password is case sensitive. You can use up to eight alphanumeric characters. Press
<Enter> after entering the password. At the next prompt, confirm the new password by retyping it and
pressing <Enter> again.
To disable the password dialog box appears. A message appears confirming that the password has been
disabled. If you have set supervisor and user Password, only the supervisor password allows you to enter
the BIOS setup program.
Note: If you forget your password, the only way to solve this problem is to discharge the CMOS
memory by turning power off and placing a shunt (jumper cap) on jumper JP2 to short pin 2
and pin 3 for five seconds, then putting the shunt back to pin 1 and pin 2 of JP2.
4.17 Save & Exit Setup
Selecting this option and pressing <Enter> will save the new setting information in the CMOS memory
and continue with the booting process.
4.18 Exit Without Saving
Selecting this option and pressing <Enter> will exit the Setup utility without recording any new values or
changing old ones.

Watchdog Timer
EBC573 User’s Manual 62 Appendix A
The EBC573 features a watchdog timer that reset the CPU or generates an interrupt if the processor
stops operating for any reason. This feature ensures system reliability in industrial standalone or
unmanned environments.
A.1 Watchdog Timer Working Procedure
The Watchdog Timer (WDT) is a special hardware device that monitors the computer system during
normal operation. The WDT has a clock circuit that times down from a set number to zero. If a monitored
item occurs before the timer reaches zero, the WDT resets and counts down again. If for some reason the
monitored item doesn’t occur before the timer reaches zero, the WDT performs an action, such as a
diagnostic operation (rebooting the computer) or generate an NMI.
You must enter timer values into the WDT Configuration Register (Write the control value to the
Configuration Port), and clear (read the Configuration Port).

A.3 Watchdog Timer Programming Procedure
Power on or reset the system
The initial value of WDT Control Register (D4~D0) is zero, when power is on or reset the system. The
following shows the initial value of WDT (00000000b):
Bit Val ue Meaning
7 0 Disable WDT
6 0 Reset output is disable
5 0 NMI output is disable
4 0 WDT Notice output is disable
3 0 Select WDT count mode by second
2, 0,1 000 Select time-out occurs after 1 second/minute
Table A-3: WDT Control Register Initial Value
Clear the WDT
The WDT counter internal cannot be longer than the preset time; otherwise, the WDT generates a NMI
(Non Maskable Interrupt) or sends a reset signal to the system.
Note: Before running WDT, clear the WDT to make sure the initial value is zero before enabling the
WDT.
WDT Control Register (Write to WDT configuration port)
Note: This register writes to the WDT configuration port.
You can set the WDT Control Register to control the WDT working mode.
Follow below instructions to set the initial value of the WDT working mode.
1. Select the WDT time out occurs time
Time-out intervals decide by values of bit 2, bit 1, bit 0 in I/O port 2E0h minute or second decide by
values of bit 3 in I/O port 2E0h
2. Enable or Disable WDT Notice Output decide by bit 4 value in I/O port 2E0h
3. Enable or Disable NMI Output decide by bit 5 value in I/O port 2E0h
4. Enable or Disable Reset Output decide by bit 6 value in I/O port 2E0h
5. Enable or Disable the WDT decide by bit 7 value in I/O port 2E0h
After finishing the above settings, you must output the Control Register’s value to the WDT
Configuration Port. Then WDT will start according to the above settings.
Note: Build a mechanism in the program to continue to read the WDT Configuration Port for
clearing WDT before time out.
