2-3. HOW TO SET JUMPERS
A jumper consists of two or three metal pins with a plastic base mounted on the card, and a small plastic
cap (with a metal contact inside) to connect the pins, so you can set up your hardware configuration by
"open" or close the pins. The jumper can be combined into sets, which called jumper blocks. When the
jumpers are all in the block, you have to put them together to set up the hardware configuration. The figure
below shows how it looks.
2 PIN
3 PIN
CAP
JUMPERS AND CAP
If a jumper has three pins, for example, label PIN1, PIN2, and PIN3, you can either connect PIN1 & PIN2 to
create one setting and shorting or connect PIN2 & PIN3 to create another setting. The jumper setting rules
are applied throughout this manual.

3-3. WATCHDOG TIMER CONFIGURATION
This section describes how to use the Watchdog Timer, including disabled, enabled, and trigger functions.
The AR-B1682 is equipped with a programmable time-out period watchdog timer. You can use your own
program to enable the watchdog timer. Once you have enabled the watchdog timer, the program should
trigger the I/O every time before the timer times out. If your program fails to trigger or disable this timer
before it times out, e.g. because of a system hang-up, it will generate a reset signal to reset the system. The
time-out period can be programmed to be set from 1 to 255 minutes.

Watchdog Block Diagram
The diskette includes a Watch Dog Zip file. In the file, there are several execution programs written in
different forms.
The sub-directories of the file are:
(1) Library and Test Program written in Assembly Language.
(2) Library and Test Program written in Turbo C++.
~ Page 23 ~
3-3-1. Watchdog Timers Setting
The watchdog timer is a circuit that may be used from your program software to detect system crashes or
hang-ups. Whenever the watchdog timer is enabled, the LED will blink to indicate that the timer is counting.
The watchdog timer is automatically disabled after reset.
Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time
before it times out. After you trigger the watchdog timer, it will be set to non-zero value to watchdog counter
and start to count down again. If your program fails to trigger the watchdog timer before time-out, it will
generate a reset pulse to reset the system.
The factor of the watchdog timer time-out constant is approximately 1 minutes. The period for the watchdog
timer time-out is between 1 to FF timer factors.
If you want to reset your system when watchdog times out, the following table listed the relation of timer
factors between time-out periods. The formula of Time-Out Period is 30+60x(Time Factor -1). For example,
if the time factor is 10. The Time-out period is calculated as 30+60x(10-1)= 570.

3-3-2. Watchdog Timer Enabled
To enable the watchdog timer, you have to output a byte of timer factor to the watchdog. The following is a
Turbo C++ program, which demonstrates how to enable the watchdog timer and set the time-out period at 1
minute.
#include “studio.h”
#include “watchdog.h”
main( )
{
char WD_TIME=0x01;
print (“Enable watchdog” );
//Set watchdog Timer Output is 30 seconds
_enable_wd (WD_TIME);
}
~ Page 24 ~
3-3-3. Watchdog Timer Trigger
After you enable the watchdog timer, your program must write the same factor as enabling to the watchdog
register at least once every time-out period to its previous setting. You can change the time-out period by
writing another timer factor to the watchdog register at any time, and you must trigger the watchdog before
the new time-out period in the next trigger. Below is a Turbo C++ program that demonstrates how to trigger
the watchdog timer:
#include “studio.h”
#include “watchdog.h”
main( )
{
char WD_TIME=0x01;
prints (“Trigger watchdog”);
//Set watchdog Timer Output is 30 seconds
_enable_wd(WD_TIME);
}
3-3-4. Watchdog Timer Disabled
To disable the watchdog timer, simply write a 00H to the watchdog register.
#include “studio.h”
#include “watchdog.h”
main ( )
{
prints (“Disable Watch Dog”);
_Disable_WD( );
}

4-1. BIOS SETUP OVERVIEW
The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the PCI
bus and connected devices such as the video display, diskette drive, and the keyboard.
The BIOS provides a menu-based interface to the console subsystem. The console subsystem contains
special software, called firmware that interacts directly with the hardware components and facilitates
interaction between the system hardware and the operating system.
The BIOS default values ensure that the system will function at its normal capability. In the worst situation
the user may have corrupted the original settings set by the manufacturer.
After the computer is turned on, the BIOS will perform diagnostics on the system and display the size of the
memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu
will show on the screen.
The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight the option
that you wish to modify, and then press the [Enter] key to select the option and configure the functions.
The AR-B1682S doesn’t contain VGA, LCD, SCSI, LAN so we can’t select the function about it in BIOS

CAUTION:
1. In the AR-B1682 BIOS the factory-default setting is the <Auto Configuration with Optimal Settings>
Acrosser recommends using the BIOS default settings, unless you are very familiar with the settings function, or
you can contact the technical support engineers (FAE).
2. If the BIOS loses the settings, the CMOS will detect the <Auto Configuration with Fail Safe Settings> to
boot the operating system. This option will reduce the performance of the system. Acrosser recommends
choosing the <Auto Configuration with Optimal Settings> in the main menu. This option gives best-case
values that should optimize system performance.
3. The BIOS settings are described in detail in this section.
~ Page 27 ~
4-2. STANDARD CMOS SETUP
The <Standard CMOS Setup> option allows you to record some basic system hardware configurations and
set the system clock and error handling. If the CPU board is already installed in a working system, you will
not need to select this option anymore.

The user can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information on
how to create this file, please refer to the MS-DOS manual.
Floppy Setup
The <Standard CMOS Setup> option records the types of floppy disk drives installed in the system.
To enter the configuration value for a particular drive, highlight its corresponding field and then select the
drive type using the left-or right-arrow key.
Hard Disk Setup
The BIOS supports various types for user settings, The BIOS supports <Pri Master> and <Pri Slave> so the
user can install up to two hard disks. For the master and slave jumpers, please refer to the hard disk’s
installation descriptions and the hard disk jumper settings.
You can select <AUTO> under the <TYPE> and <MODE> fields. This will enable auto detection of your IDE
drives during boot up. This will allow you to change your hard drives (with the power off) and then power on
without having to reconfigure your hard drive type. If you use older hard disk drives, which do not support
this feature, then you must configure the hard disk drive in the standard method as described above by the
<USER> option.
Boot Sector Virus Protection
This option protects the boot sector and partition table of your hard disk against accidental modifications. Any
attempt to write to them will cause the system to halt and display a warning message. If this occurs, you can either
allow the operation to continue or use a bootable virus-free floppy disk to reboot and investigate your system. The
default setting is <Disabled>. This setting is recommended because it conflicts with new operating systems.
~ Page 28 ~
Installation of new operating systems requires that you disable this to prevent write errors.
4-3. ADVANCED CMOS SETUP
The <Advanced CMOS Setup> option consists of configuration entries that allow you to improve your
system performance, or let you set up some system features according to your preference. Some entries
here are required by the CPU board’s design to remain in their default settings.

Floppy Access Control
This option determines the floppy access method, which can be either read only or normal (read/write).
When set to read only, the data in the floppy is allowed to read instead of being written.” Normal” allows the
floppy to be read or written.
HDD Access Control
This option determines the hard disk access method, which can be either read only or normal (read/write).
When set to read only, the data in the hard disk is allowed to read instead of being written.” Normal” allows
the floppy to be read or written.
Available options: Disabled, Enabled
S.M.A.R.T for hard Disks
S.M.A.R.T is abbreviation of Self-Monitoring Analysis and Reporting Technology .It is reliable and
precautious technology. When Hard Disk disorder, it prevents Hard Disk from the loss of data.
Boot Up Num-Lock
This item is used to activate the Num-Lock function upon system boot. If the setting is on, after a boot, the
Num-Lock light is lit, and the user can automatically use the number keys.
Floppy Drive Swap
The option reverses the drive letter assignments of your floppy disk drives in the Swap A, B setting,
otherwise leave on the setting to Disabled (No Swap). This works separately from the BIOS Features floppy
disk swap feature. It is functionally the same as physically interchanging the connectors of the floppy disk
drives. When <Enabled>, the BIOS swaps the floppy drive assignments so that Drive A becomes Drive B,
and Drive B becomes Drive A under DOS.
Floppy Drive Seek
If the <Floppy Drive Seek> item is set to Enabled, the BIOS will seek the floppy <A> drive one time upon
boot up.
PS/2 Mouse Support
The setting of Enabled allows the system to detect a PS/2 mouse on boot up. If detected, IRQ12 will be
used for the PS/2 mouse. IRQ 12 will be reserved for expansion cards if a PS/2 mouse is not detected.
Disabled will reserve IRQ12 for expansion cards and therefore the PS/2 mouse will not function.
Typematic Rate
This item specifies the speed at which a keyboard keystroke is repeated.
System Keyboard
The setting of <Absent> allows the system to boot without a keyboard attached to the computer; the setting
of <Present> is in the contrary.
Primary Display
The setting of <Absent> allows the system to boot without a Primary Display attached to the computer; the
setting of <Present> is in the contrary.
Password Check
This option enables password checking every time the computer is powered on or every time the BIOS
Setup is executed. If Always is chosen, a user password prompt appears every time the computer is
turned on. If Setup is chosen, the password prompt appears if the BIOS are executed.
Boot to OS/2 >64MB
When using the OS/2 operating system with DRAM of greater than 64MB installed, you need to Enabled this
option; otherwise leave this on the setup default of Disabled.
