0.7 STATIC ELECTRICITY PRECAUTIONS
Before removing the board from its anti-static bag, read this section about static electricity precautions.
Static electricity is a constant danger to computer systems. The charge that can build up in your body may be
more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic
precautions whenever you use or handle computer components. Although areas with humid climates are much
less prone to static build-up, it is always best to safeguard against accidents that may result in expensive repairs.
The following measures should be sufficient to protect your equipment from static discharge:
! Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded
wrist strap).
! When unpacking and handling the board or other system components, place all materials on an anti-static
surface.
! Be careful not to touch the components on the board, especially the “golden finger” connectors on the
bottom of the board.

Jumper pins allow you to set specific system parameters. Set them by changing the pin location of the jumper
blocks. (A jumper block is a small plastic-encased conductor that slips over the pins.) To change a jumper
setting, remove the jumper from its current location with your fingers or small needle-nosed pliers. Place the
jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful
not to bend the pins.
We will show the locations of the AR-B1662 jumper pins, and the factory-default settings.
CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a grounded wrist
strap or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can
permanently damage electronic components.

4.1 WATCHDOG TIMER SETTING
The watchdog timer is a circuit that maybe be used from your program software to detect crash or hang up.
The Watchdog timer is automatically disabled after reset. Once you enabled the watchdog timer, your program
should trigger the watchdog timer every time before it times out. After you trigger the watchdog timer, the timer will
be set to zero and start to count again. If your program fails to trigger the watchdog timer before times out, it will
generate a reset pulse to reset the system or trigger the IRQ 9 signal in order to tell your system that the watchdog
time is out.
Please refer to the following table in order to properly program Watchdog function
D7 D6 D5 D4 D3 D2 D1 D0
1 Enable Reset
Time period
0 Disable IRQ 9
Users could test watchdog function under ‘Debug’ program as follows:
C:>debug
# O 443 C8H
Generally, watchdog function would reset system after 8 seconds
# O 443 0H
Disable watchdog function
C:>debug
# O 443 88H
Generally, watchdog function would generate IRQ 9 after 8 seconds
# O 443 0H
Disable watchdog function
4.2 WATCHDOG TIMER TRIGGER
After you enable the watchdog timer, your program must write the same factor as triggering to the watchdog timer
at least once during ev ery time -out period . You can change the time-out per iod by w riting an other tim er factor to th e
watchdog register at any time, and you must trigger the watchdog during every new time-out period in next trigger .

5.1 BIOS SETUP OVERVIEW
The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the ISA 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 ensur e that th e sy ste m will function at its normal capability. In the worst situat ion th e us e r
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 o ptions. Use the [Up/Down] arrow key to highlight the opti on that y ou
wish to modify, and then press the [Enter] key to select the option and configure the functions.

CAUTION:
1. AR-B1662 BIOS the factory-default setting is used to the <Auto Configuration with Optimal Settings>.
Acrosser recommends using the BIOS default setting, unless you are very familiar with the setting function, or
you can contact the technical support engineer.
2. If the BIOS settings are lost, the CMOS will detect the <Auto Configuration with Fail Safe Settings> to boot the
operation system, this option will reduce the performance of the system. Acrosser recommends choosing the
<Auto Configuration with Optimal Setting> 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.
5.2 STANDARD CMOS SETUP
The <Standard CMOS Setup> option allows you to record some basic system hardware configuration 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.
Standard CMOS Setup
Date & Time Setup
Highlight the <Date> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current date.
Follow the month, day and year format.
Highlight the <Time> field and then press the [Page Up] /[Page Down] or [+]/[-] keys to set the current date.
Follow the hour, minute and second format.
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.
Hard Disk Setup
The BIOS supports various types for user settings, The BIOS supports < Pri Master>, < 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 in section three of this manual.
<Sec Master>, <Sec Slave> is reserv ed to Compa ct Flas h, user can set CF in mas ter mode or slave m ode by J102
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.
