This cha pter of the User’s Manual describes how to set jumpers.
Note: The procedu res that follow are generic for all of the NEX732L 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 pre vent you from accidentally damaging the internal components.
Most of the proce dures that follow require only a few simple tools, including the following:
w A Philips screwdriver
w A flat-tipped screwdriver
w A set of jewelers Screwdrivers
w A grounding strap
w An anti-static pad
Using your f ingers can disconnect most of the connections. I t is recommended that you do not use
needle-nosed pliers to d isconnect 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 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 w arranted whenever danger of static electricity exists.
2.2 Precaut ions
Computer components and electronic circuit boards can be damaged by discharges of static electricity.
Working on the computers that are still conne cted to a power supply can be extremely dangerous. Follow
the guidelines below to avoid damage to your computer or yourself:
w Always disconnect the unit from the power outlet wh enever you are working inside the case.
w If p ossible, wear a gro unded 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 o f any other grounded appliance.
w Hold electronic circuit boards (such as the NEX732L board) by the edges only. Do not touch the
components on the board un less it is necessary to do so. Don’t flex or stress the circuit board.
w Leave all componen ts inside the static-proo f packaging that they shipped with un til they are ready
for installation.
w Use correct screws and do not over tighten screws.

2.3 Setting Jum pers
A jumper is the simplest kind of electric switch. It con sists 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.

This chapter explains how to use the BIOS Setup program for the NEX732L2G. The current BIOS setup
pictures in the cha pter is for reference only, which may change by the BIOS modification in the future. User
ca n download any major updated items or reversion from NEXCOM web site http://w ww.nexcom.com.tw . If
a ny unclear message occurs, please contact NEXCOM custo mer service representative for help or log onto
http://www.nexcom.com.tw/contact/contact.h tm.
4.1 About the BIOS
The BIOS (Basic In put and Output System) Setup program is a menu driven utility that enables you to make
cha nges to the system configuration and tailor your system to suit your individual work needs. It is a ROMbased configu ration utility that displays the system’s configuration status and provides you with a tool to set
system p arameters. 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:
w Hard drives, diskette drives, and pe ripherals
w Video display type and display options
w Password protection from unauthorized use
w Power management features
The settings made in the Setup program intimately affect how the computer performs. It is important,
therefore, f irst to try to u nderstand all the Setup options, and seco nd, to make settings appropriate for the
way you use the computer.
4.2 When to R un BIOS
This program should be executed under the following conditions:
w W hen changing the system configuration
w W hen a configuration error is detected by the system and you a re prompted to make changes to
the Setup program
w W hen resetting the system clock
w W hen setting the CPU clock speed so that it automatically runs either fast or slow
w W hen redefining the communication ports to prevent any conflicts
w W hen making changes to the Power Management configuration
w W hen changing the password or making other cha nges to the security setup
Normally, CMOS setup is needed when the system hardw are is not consistent with the information contained in the C MOS RAM, whenever the CMOS RAM has lost power, or the system features need to be
changed.
30 Chapter 4NEX73 2L2G User Manual
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:
w If the error occurs before the display device is initialized, a series of bee ps will be transmitted.
w 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 Setu p 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 <Es c> keys to enter Setup:

4.9 Advanced Chipset Features
Since the f eatures in this section are related to the chipset in the C PU board and all are optimized, you are
not recommended to change the default settings in the setup table, unless you understa nd the chipset
featu res.
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 betwee n 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 chang es 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 be en carefully chosen and should only be altered if data is being lost. Such a scenario might
well o ccur 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 Featu res on the main program screen displays this menu:

4.11 Power Managem ent Setup
This option lets you control system power man agement. 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 certa in events.
The pow er-saving modes can be controlled by timeouts. If the system is inactive for a time, the timeouts
begin counting. If the in activity continues so that the timeout period elapses, the system enters a powersaving mode. If an y item in the list of Reload Global Timer Events is enabled, then any activity on that item
will reset the timeout coun ters to zero.
If the system is suspe nded or has been powered down by software, it can be resumed by a wake up call that
is g enerated 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 th e main program screen displays this m enu:

Watchdog Timer
61 Appendix ANEX73 2L2G User Manual
The NEX732L series feature s a watchdog timer that reset the CPU or generates an interrupt if the processor
stop s operating for any reason. This feature ensures system reliability in ind ustrial standalone or unmanned
environments.
A.1 W atchdog Timer Working Procedure
The Watch dog Timer (WDT) is a special hardware device that monitors the computer system during normal
operation. The WDT ha s 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 ite m doesn’t occur before the timer reaches zero, the WDT performs an action, such as a diagnostic o peration (rebooting the computer) or generate an NMI.
You must ente r timer values into the WDT Configuration Register (Write the control value to the Configuration Port), and clea r (read the Configuration Port).
