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 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.

3.11 SRAM. MEMORY BANK ADDRESS SELECT (XP3)
This section provides the information about how to use the SRAM. It divided into two parts: hardware setting and
software configuration.
Step 1: Use XP3 to select the correct SRAM memory address.
Step 2: Insert programmed SRAM into IC U18 setting as SRAM.
The hardware divides every 16KB of memory into a memory bank. User to assign a bank number,
Memory bank start from 00, last memory bank number depends on the size to the SRAM chip.
If on board the 512KB SRAM chip, the memory bank in the range of 00 to 31. The SRAM I/O Port = 78H.
Example: Select the 10th bank of the U18. Using 512K*8, the I/O port =78H
Answer 1:(in assembly language)
MOV DX, 78H ; AR-B9673’s I/O port=78h
MOV AL, 10 ; Selection the 10th bank

4. WATCHDOG TIMER
This section describes the use of Watchdog Timer, including enable, and trigger. AR-B9673 is equipped with a
programmable time-out period watchdog timer that occupies I/O port 3F0/3F1. Users can use simple program to
enable the watchdog timer. Once you enable the watchdog timer, the program should trigger it every time before it
times out. Watchdog Timer will generate a response (system or IRQ15) due to system fails to trigger watchdog timer
before preset timer, times out.
System reset and IRQ15 reset signal command as follows:
- o 3F0 72 ; Used system reset signal
- o 3F1 00
- o 3F0 72 ; Used IRQ15 signal
- o 3F1 0F
- o 3F0 F2 ; Set timer for xx second (xx=0 ~ 255)
- o 3F1 xx

4.1 WATCHDOG FOR IRQ15 SIGNAL SETTING
If you program the watchdog to generate IRQ15 signal when it times out, please refer to I/O port and time factor
table as follows:
I/O port: 76H
For example: out 76h, 31h
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 period in next trigger.
5. BIOS CONSOLE

 Boot
 Exit
5.1 BIOS SETUP NOTICE
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.

CAUTION:
1. AR-B9673 BIOS the factory-default setting is used to the <Optimized Defaults> 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 system will detect the <COMS checksum error> and boot the operation system,
that situation will reduce the performance of the system. Acrosser recommends you to reset the <Optimized
Defaults>. This option gives best-case values that should optimize system performance.
3. The BIOS settings are described in detail in this section.
5.2 MAIN CMOS SETUP
The <Main 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.
