Chapter 2
Jumper Setting
13
This chapter of the User M anual describes how to set jumpers.
Note: The procedures that follow are generic for all NEX852 models
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 Phillips 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, ma ke sure that the power is of f. 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 extre mely 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 a s the NEX852 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 pack aging that they shi pped with until they are rea dy
for installation.
Use correct screws and do not over tighten screws.

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
35
35
This chapter explains how to use the BIOS Setup program for the NEX852VL2. The current BIOS setup
pictures in the cha pter is for reference only, which may change by the BIOS modification in the future. Users
can download a ny major updated items or reversion from NEXCOM web site http://www .nexcom.com.tw. If
any unclear message occurs, please contact NEXCOM customer service repre sentative 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-ba sed configuration utility that displays the system’s conf iguration 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 syste m 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 option s
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 setting the CPU clock speed so that it automatically runs either fast or slow
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.
36
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-ESC> OR <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 A ward BIOS CMOS Setup Utility, the Main Menu (Figure 1) will appear on the screen. The
main menu allows you to select from ten setup functions and two exit choices. Use arrow keys to select

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 perf ormance or set up system feature s a ccording to your preference, without causing
fatal errors to your system.
Figure 4-3: BIOS – Advanced BIOS Features
The following explains the options f or ea ch feature:
Virus Warning
Allow you to choose the Virus W arning fe ature f or IDE Hard Disk boot sector protection. If this function is
enabled a nd someone attempts to write data into this area, BIOS will show a warning message on screen
and a n alarm will beep.
42
Enabled: Activate s automatically when the system boots up causing the following warning
!WARNING!
Disk boot sector is to be modified
Type “Y” to accept write or “N” to abort write
Award Software, Inc.
message to a ppear when anything attempts to access the boot sector or hard disk partition ta ble:
Disabled: No warning me ssage will appear when an attempt is made to access the boot sector or
hard disk partition table.
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 and L2
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 and Level 2 cache. Naturally, the
default and recommended setting is En abled.
First/Second/Third Boot Device
BIOS attempts to load the operating system from the devices in the sequence selected. The available
choices are: Floppy, LS120, HDD-0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, ZIP100, USB-FDD, USBZIP, USB-CDROM, USB-HDD, LAN, and Disabled.
Boot Up Floppy Seek
Enable this to allow the system to search f or floppy drives during the POST. Disa ble this item to boot fa ster.
Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key when the syste m boot. If On, the numeric
keypad is in numeric mode. If Off, the numeric keypad is in cursor control mode.
Typematic Rate Setting
43
If set to Enabled, enable s you to set the Typematic Rate and T ypematic Delay. When Disa bled, the f ollowing two items (T ypematic Rate and T ypematic Delay) are irreleva nt. Keystroke repeats at a rate determined
by the keyboard controller in your system.
Typematic Rate (Chars/Sec): When the typematic rate setting is Enabled, you can select a
typematic rate (the rate at which character re peats when you hold down a key) of 6, 8, 10, 12, 15,
20, 24, or 30 characters per second.
T y pe matic Delay (Msec): This setting controls the ti me between the display of the first character
and successive characters. There are four delay choices: 250ms, 500ms, 750ms and 1000ms.
Security Option
Enables you to sele ct whether the pa ssword is required every ti me 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 pa ssword 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.
MPS Version Control for OS
This feature is only applicable to multiprocessor motherboards as it specifies the version of the MultiProcessor Specification (MPS) that the motherboard will use. The MPS is a specification by which PC
manufa cturers design a nd build Intel archite cture systems with two or more processors. MPS version 1.4 is
required for a motherboard to support a bridgeless secondary PCI bus.
OS Select for DRAM>64MB
Set to OS2 if the system memory size is greater than 64 MB and the operating system is OS/2, otherwise
select non-OS2 option.
Spread Spectrum
The BIOS usually offers two levels of modulation - 0.25% or 0.5%. The greater the modulation, the
greater the reduction of EMI. Therefore, if you need to signif ica ntly reduce your motherboard's EMI, a
modulation of 0.5% is recommended.
In most conditions, frequency modulation via this feature should not cause a ny problems. However,
system stability may be slightly compromised in certain situations. For example, this BIOS feature may
cause improper functioning of timing-critical devices like clock-sensitive SCSI devices.
Spread Spectrum can also cause problems with overclocked systems, especially those that have been
taken to extremes. Even a slight modulation of frequency may cause the processor or any other
overclocked components of the system to fail, leading to very predictable consequences.
44
Therefore, it is recommended that you disable this feature if you are overclocking your system. The risk
of cra shing your system is not worth the reduction in EMI. Of course, if EMI reduction is important to
you, enable this feature by all means. But you should reduce the clock speed a little to provide a margin
of safety.
After you have made your selections in the Adva nced BIOS Feature s setup, press <ESC> to go ba ck to the
main screen.
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 ma nage bus speeds and access to system memory resources, such as DRAM a nd 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 ma king a ny cha nges would be if you discovered that data wa s be ing lost while
using your system.
The first chipset settings deal with CPU access to dynamic ra ndom 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 progra m screen displays this menu:
Figure 4-4: BIOS – Advanced Chipset Features
45
System BIOS cacheable
Selecting Enabled allows ca ching of the system BIOS ROM at F0000h-FFFFFh, resulting in better syste m
performance. However, if any progra m writes to this me mory area, a system error may result. The availa ble
choices are Enabled, Disabled.
Video BIOS Cacheable
Selecting Enabled allows ca ching of the video BIOS ROM at C0000h, resulting in better video perf ormance.
However, if any program writes to this memory area, a system error may result. The choices: Enabled,
Disabled.
Memory Hole At 15M – 16M
In order to improve performa nce, certain spa ce in memory is re served for ISA cards; This memory must be
mapped into the me mory.
The choices: Enabled, Disa bled.
Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support complia nce with PCI specif ication version 2.1.
On-Chip VGA
By default, the On-Chip VGA or chipset-integrated VGA is Enabled.

Onboard Serial Ports (1, 2)
This feature allows you to manually select the I/O a ddress a nd IRQ f or the first a nd second seri al ports. It is
recommended that you leave it a s 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 ca n ma nually select a n altern ative I/
O port or IRQ for it. You can also disable this seri al 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 ca n then be re allocated for other devices to use.
UART Mode Select
Select an operating mode f or the serial port.
The choices are: Normal, IrDA, ASKIR.
UR2 Duplex Mode
In an infrared port mode, this field a ppears. Full-duplex mode permits simulta neous two-direction transmission.
Half-duplex mode permits tra nsmission in one dire ction only at a ti me. 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 a nd 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, a nd 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.

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 ina ctivity continues so that the timeout period elapses, the system enters a powersaving mode. If any item in the list of Reloa d Global T i mer Events is en abled, 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 ca n be resumed by a wa ke 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 Man agement Setup on the main program screen displays this menu:

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: Ena bled a nd Disabled.
Video Off Method
This determines the manner in which the monitor is blanked. There are three choices:
1. V/H SYNC+Blank: This sele ction will cause the system to turn of f the vertical and horizontal
synchronization port and write bla nks to the video buf fer.
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 Ma n agement
signaling (DPMS) standard of the Video Electronics Sta ndard to select video power ma n agement
values.
Video Off In Suspend
This determines the manner in which the monitor is blanked. The choices: Yes, No.
MODEM Use IRQ
This determines the IRQ in which the MODEM can use. The choices are 3, 4, 5, 7, 9, 10, 11, and NA

After the selected period of system ina ctivity , all devices exce pt 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 ina ctivity, the hard disk drive powers down while all other devices remain
active.
Soft-Off by PWR-BTTN
This function can turn the system off with the on/off button places the system in a very low-power-usage
state, with only enough circuitry receiving power to detect power button a ctivity or Resume by Ring a ctivity.
The choices are Delay 4 seconds, a nd In sta nt-Off.
52
Wake up by PCI Card
When the system enters a Soft-off mode (Standby power exist but syste m is not working), it will wake up
system when specific signals occurred. The BIOS monitors the syste m f or “activity” to determine when to
enable power ma nagement.
If you enable this feature, the computer specifie s that any signal noticed on the PCI (Peri pheral Component
Interconnect) bus channel must make go out from the hibernation state. The choices: Enabled, Disabled.
Power On by Ring
An input signal on the serial Ring Indicator (RI) line (in other words, an incoming call on the modem)
awakens the syste m from a soft off state. The choice s: Ena bled, Disabled.
Reload Global Timer Events
Primary/Secondary IDE 0/1
FDD, COM, LPT Port
PCI PIRQ [A-D]#
The events are I/O events whose occurrence can prevent the system from entering a power saving mode
or can awa ken the system from such a mode. In ef fect, the system remain s alert for a nything, which occurs
to a device, which is configured a s Ena bled, even when the system is in a power down mode. The choices
are Enabled, a nd 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 se ction covers some very technical ite ms and it is strongly recommended that only experienced users should make a ny changes to the default settings.
Selecting PnP/PCI Configurations on the main program screen displays this menu:
53
Figure 4-10: BIOS – PnP/PCI Configurations
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 a nd the system re configuration 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 a nd Play BIOS ha s the capacity to automatically configure all of the boot and Plug a nd Play
compatible devices. However, this capability means absolutely nothing unless you are using a Plug and
Play operating system such as going into e a ch of the submenus that follows this f ield. The choices are Auto
(ESCD), Manual.
4.13 PC Health Status
When main boards support hardware monitoring, this item lets you monitor the parameters for critical
voltages, critical temperatures, and fa n speeds. These are the re ad only ite ms.
After you have read the PC Health Status, press the <ESC> key to go back to the main program screen.
4.14 Load Fail-Safe Defaults
This option opens a dialog box that lets you install fail-safe defaults f or 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.
54
4.15 Load Optimized Defaults
This option opens a dialog box that lets you install opti mized defaults f or 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 perf ormance level of the components, such as the CPU a nd 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 pa ssword disa bled. If you
want to cha nge the pa ssword, you must f irst enter the current pa ssword, then at the prompt enter your new
password. The pa ssword is ca se sensitive. Y ou ca n use up to eight alpha numeric chara cters. 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 pa ssword 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 a nd placing a shunt (jumper cap) on jumper JP2 to short pin 2 a nd 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 inf ormation in the CMOS memory a nd
continue with the booting process.
4.18 Exit Without Saving
Selecting this option and pressing <Enter> will exit the Setup utility without re cording any new values or
changing old ones.
This concludes Chapter 4. The next chapter covers drivers installing.

Watchdog Timer
56
56
The NEX852VL(2) fe atures a watchdog timer that re set the CPU or generates a n interrupt if the processor
stops operating for any re a son. This feature en sures system reli ability in industri al standalone or un ma nned
environments.
A.1 Watchdog Timer Working Procedure
The Watchdog Ti mer (W DT) is a speci al 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 ti mer re aches zero, the WDT perf orms an action, such a s a diagnostic operation (rebooting the computer) or generate an NMI.
Y ou must enter ti mer values into the WDT Configuration Register (Write the control value to the Configuration Port), and clear (rea d the Configuration Port).
