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.  
CAP  
2 PIN  
3 PIN  
JUMPERS AND CAP  
If a jumper has three pins, for example, labelled 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.  
~ Page 7 ~  
 
2-4. SYSTEM CLOCK SELECT AND CPU SETTING  
System clock and CPU frequency ratio are automatically detected by BIOS. Please keep sw2 ,  
sw3-1 , sw3-2 ,and sw3-3 off.

A 32-pin DOC socket supports a DOC (Disk-on-Chip) up to 72Mb. This PnP Flash ROM DOC can  
be installed as one of the user’ s hard disk drive. And if set as Drive C, it can be used to boot up  
the computer with MS-DOS installed. It offers much faster access than a floppy or hard disk and  
greatly increases reliability under harsh environment.

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++  
3-3-1. Watchdog Timer Setting  
The watchdog timer is a circuit that may be used from your program software to detect system crashes or  
hang-ups. LED1 on this CPU board is the watchdog timer indicator, which is located at the upper-right corner  
above the 5-pin multi-function connector. 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.  
~ Page 23 ~  
 
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 period. 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 24  
seconds.  
#Include “ stdio. H”  
#include WATCHDOG.H”  
main( )  
{
char WD_TIME=oxo1;  
printf (“ Enable watchdog” );  
//Set watchdog Timer Output is 30 seconds  
_enable_wd (WD_TIME);  
}
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 which demonstrates how to trigger the  
watchdog timer:  
#include “ stdio.H”  
#include WATCHDOG.H”  
main( )  
{
char WD_TIME=oxo1;  
printf (“ Trigger watchdog” );  
//Set watchdog Timer Output is 30 seconds  
_enable_wd(WD_TIME);  
}
~ Page 24 ~  
 
3-4-4. Watchdog Timer Disabled  
To disable the watchdog timer, simply write a 00H to the watchdog register.  
#include “ stadio.H”  
#include WATCHDOG.H”  
main ( )  
{
printf (“ 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.

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 29 ~  
 
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 bootup. 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. Installation of a new operating systems requires that you disable this to prevent write  
~ Page 30 ~  
 
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.

APPENDIX C  
TROUBLE SHOOTING  
TROUBLE SHOOTING FOR ERROR MESSAGES  
The following information will present the resolution of trouble encountered as well as the error messages.  
Adjust the system following the messages below and make sure all the components & connectors are in  
proper position and firmly attached. If the error still remains, contact with your distributor for maintenance.  
POST BEEP :  
There are two kinds of beep codes in BIOS. One code indicates that a video error has occurred and the BIOS  
cannot initialize the video screen to display any additional information. This beep code contains a single long  
beep followed by three short beeps. The other code indicates that DRAM error has incurred. This beep code  
appears a single long beep repeatedly.  
CMOS BATTERY FAILURE :  
When the CMOS battery is out of work or has run out, the user has to replace it with a new battery same as  
the old one.  
CMOS CHECKSUM ERROR :  
When the battery runs weak, CMOS will be corrupted. Check the battery and change a new one when  
necessary.  
DISPLAY SWITCH IS SET INCORRECTLY:  
Display switch on the motherboard can be set to either monochrome or colour, which indicates the switch is  
set to a different setting from the indicated in Setup. Determine which setting is correct, and then either turn  
off the system and change the jumper, or enter Setup and change the video selection.  
DISK BOOT FAILURE:  
When boot device isn’ t available, insert a system disk into Drive A and press < Enter >. Make sure both the  
controller and cables are all in proper positions, also make sure the disk is formatted correct device. Then  
reboot the system.  
DISKETTE DRIVES OR TYPES MISMATCH ERROR :  
If the diskette drive type is different from CMOS, run setup and correct it .  
ERROR ENCOUNTERED INITIALIZING HARD DRIVE :  
When hard drive can’ t be initialized, make sure the adapter is installed correctly and all cables are properly  
and firmly attached. Also be sure the correct hard drive type is selected in Setup.  
ERROR INITIALIZING HARD DISK CONTROLLER:  
When error occurs, be sure the cord is exactly installed in the bus and the correct hard drive type is selected  
in Setup. Besides that, check whether all of the jumpers in the hard drive are set correctly.  
FLOPPY DISK CONTROLLER ERROR OR NO CONTROLLER PRESENT:  
When fail to find or initialize the floppy drive controller, check whether the controller in proper station. If there  
are no floppy drive installed, Ensure the Diskette Drive selection in Setup is set to NONE.  
KEYBOARD ERROR OR NO KEYBOARD PRESENT :  
When it happens, make sure keyboard properly attached and no keys being pressed during booting. If you are  
purposely configuring the system without a keyboard, enter <ADVANCED CMOS SETUP>and choose  
<Absent>at the item<System Keyboard>, BIOS will ignore the missing keyboard and continue the booting.  
~ Page54 ~  
 
MEMORY ADDRESS ERROR:  
While the memory address error revealed, trace the error location with the memory map in system and  
replace the bad memory chips.  
MEMORY SIZE HAS CHANGED:  
Memory has been added or removed since the last boot. In EISA mode, re-configure the memory configuration  
by using Configuration Utility. While in ISA mode, enter Setup and enter the new memory size in the memory  
fields.  
MEMORY VERIFYING ERROR:  
It indicates an error verifying value has been written to memory. Use the location along with system's memory  
map to locate the bad chip.  
OFFENDING ADDRESS MISSING:  
This is related to the I/O CHANNEL CHECK and RAM PARITY ERROR when the segment cannot be isolated.  
REBOOT ERROR:  
When error occurs, press any key to reboot the system.  
SYSTEM HALTED :  
This message indicates the present boot has failed. Press and hold down Ctrl, Alt and Del simultaneously to  
reboot the system.
