0.6 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 pron e 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, pl ace 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
z O 443 C8H
Generally, watchdog function would reset system after 8 seconds
z O 444 0
Disable watchdog function
C:>debug
z O 443 88H
Generally, watchdog function would generate IRQ 9 after 8 seconds
z O 444 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 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.
Setup Main Menu
CAUTION:
1. AR-B1640 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 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>, <Sec Master>
and <Sec 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> 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.
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>. This setting is recommended because it conflicts with new operating systems.
Installation of new operating systems requires that you disable this to prevent write errors.

5.3 ADVANCED CMOS SETUP
The <Advanced CMOS Setup> option consists of configuration entries that allow you to improve yo ur 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.
Advanced CMOS Setup
Quick Boot
This category speeds up Power On Self Test (POST) after you power on the computer. If it is set to Enabled,
BIOS will shorten or skip some check items during POST.
1st Boot Device

4th Boot Device
These options determine where the system looks first for an operating system.
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 pr ecautious
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 user can use the number key.
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 of 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 swapped floppy drive assignments so that Drive A becomes Drive B, and Drive B becomes Driv e 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 u p.

AR-B1640 User’s Guide
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.
Primary Display
The option is used to set the type of video display card installed in the system.
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 executed.
Boot to OS/2
When using the OS/2 operating system, you need to Yes this option otherwise leave this on the setup default of No.
System BIOS Cacheable
Enabled this option to enhance system performance by shadowing and caching system BIOS shadow functions will
be ignored.
Shadow Memory
Each of segments provides three options Disabled, Enabled, and Cached for faster adapter ’s ROM executions.
However this shadow function is Chipset oriented and dependent on system hard ware feature. In general, C000
64K will be allocated for VGA BIOS and set to Cached to get higher display performance by shadowing and caching
feature. If user chooses Enabled setting, only BIOS shadow function is active.

bus slots.
PCI / Plug And Play
Plug and Play Aware O/S
Set this option to Yes if the operating system installed in the computer is Plug and Play-aware. The BIOS only
detects and enables PnP ISA adapter cards that are required for system boot. The Windows 95 operating system
detects and enables all other PnP-aware adapter cards. Windows 95 is PnP-aware. Set this option <No> if the
operating system (such as DOS, OS/2, Windows 3.x) does not use PnP. You must set this option correctly or
PnP-aware adapter cards installed in your computer will not be configured properly.
Clear NVRAM
This sets the operating mode of the boot block area of the BIOS FLASH ROM to allow programming in the Yes
setting.
PCI Latency Timer (PCI Clocks)
This option sets latency of all PCI devices on the PCI bus. The settings are in units equal to PCI clocks.
Primary Graphic Adapter
This option is set to use PCI bus or AGP. The AGP mode will get system a faster processing speed.
DMA & IRQ
These options specify the bus that the named IRQs/DMAs lines are used on. These options allow you to specify
IRQs/DMAs for use by legacy ISA adapter cards. These options determine if the BIOS should remove an IRQ/DMA
from the pool of availability of IRQs/DMAs passed to the BIOS configurable devices. If more IRQs/DMAs must be
removed from the pool, the end user can use these PCI/PnP Setup options to remove the IRQ/DMA by assigning
the option to the ISA/EISA setting. The onboard I/O is configurable with BIOS.
