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 compo nents. Although areas with humid climates are much
less prone to static build-up, it is always best to safeguard against accid ents that may result in expens ive repairs.
The following measures should be sufficient to protect your equipment from static discharge:
 Touch a grounded metal obje ct 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.

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 every time-out period. 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 during every new time-out peri od 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 cons ole subs ystem 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.

Setup Main Menu

CAUTION:

1. AR-B1651 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 famili ar 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 choos ing 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.

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 AUT OEXEC.BAT file. For information on h ow 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.

You can select <AUTO> under the <TYPE> and <MODE> fiel ds. This will enable auto detection of your IDE
drives during boot-up. T his will allow you to change your hard drives (with the power off) and then power on
without having to reconfigure your hard drive t ype. 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.

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.

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>. T his setting is recomm ende d because i t conflicts with new operating systems.
Installation of new operating systems requires that you disable this to prevent write errors.

leave on the setting of Disabled (No Swap). T his 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 swapped 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 setting 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 wi ll
reserve IRQ12 for expansion cards and therefore the PS/2 mouse will not function.
