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. Therefore, it is very 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).
• W hen 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.

1.4 POINT FOR ATTENTION DIMENSIONS
The AR-B1423A CPU is a consumer II with C4 as a version that included some bugs on it. The effect is the use of
floppy in WIN95 would be unable. The bug can be revised in CPU with C5 as a version. But according to ST as
the original manufacturer, C5 just can normally be produced at least in October. The bug still exists so it is better
to use the C4. Therefore, we decided to adopt no support as our temporary strategy.
In AR-B1423B section, we have to install WIN 95, and then set up the Floppy driver as the additional step in order
to drive the AR-B1423B Floppy device properly.
The AR-B1423A& AR-B1423B can access from 64MB to 128MB of external memory.

2.5 INTERRUPT CONTROLLER
Most of the IPC signals are multiplexed: Interrupt inputs, DMA Request inputs, DMA Acknowledge outputs. The
figure below describes a complete implementation of the IRQ [15:0] time multiplexing. When an interrupts line is
used internally, the corresponding input can be grounded. In most of the embedded designs, only few interrupts
lines are necessary and the glue logic can be simplified.
Typical IRQ multiplexing
When the interface is integrated into the STPC, the corresponding interrupt line can be grounded as it is connected
internally.
For example, if the integrated IDE controller is activated, the IRQ [14] and IRQ [15] inputs can be grounded.

AR-B1423 User’s Guide
2.6 DMA CONTROLLER
! DMA channel
! 2X8237/AT compatible 7-channel DMA controller integrated into the STPC.
! 2X8259/AT compatible interrupt Controller integrated into the STPC.

! Co-processor error support logic.
The figure below describes a complete implementation of the external glue logic for DMA Request timemultiplexing and DMA Acknowledge demultiplexing. Like for the interrupt lines, this logic can be simplified when
only few DMA channels are used in the application. T his glue logic is not needed in Local bus mode and it does not
support DMA transfers.

3.1 OVERVIEW
AR-B1423 is a 486 Grade CPU Board, which supports Ethernet, DOC, SSD, and Compact Flash (AR-B9462A) (option)
functions. This section provides the hardware’s jumper settings, the connectors’ locations, and the pin assignments.
External System Location
3.2 SYSTEM SETTING
Jumper pins allow you to set specific system parameters. Set them by changing the pin location of 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.
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.

3.3.1 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
Users could test watchdog function under ‘Debug’ program as follows:

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.
CAUTION:
Figure 5-1 BIOS: Setup Main Menu
1. AR-B1423 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.
