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.

2.1 MICROPROCESSOR
The AR-B1570 uses the NS GEODE GX1 CPU, it is an advanced 32-bit x86 compatible processor offering high
performance, fully accelerated 2D graphics, a 64-synchronous DRAM controller and a PCI bus controller, all on a
single chip. This latest generation of the MediaGX processor enables a new class of premium performance
notebook/desktop, and IPC computer designs.
The MediaGX MMX enhanced processor companion chips provide advanced video and audio functions and permit
direct interface to memory. This high-performance 64-bit processor is x86 instruction set compatible and supports
MMX technology.
This processor is the latest member of the NS MediaGX family, offering high performance, fully accelerated 2D
graphics, synchronous memory interface and a PCI bus controller, all on a single chip. As described in separate
manuals, the CS5520 and the CS5530 I/O Companion chips fully enable the features of the MediaGX processor
with MMX support. These features include full VGA and VESA video, 16-bit stereo sound, IDE interface, ISA
interface, SMM power management, and AT compatibility logic. In addition, the newer CS5530 provides an Ultra
DMA/33 interface, MPEG2 assist, and is AC97 Version 2.0 audio compliant.
In addition to the advanced CPU features, the MediaGX processor integrates a host of functions, which are
typically implemented with external components. A full-function graphics accelerator provides pixel processing and
rendering functions.
The NS MediaGX MMX-Enhanced Processor represents
a
new generation of x86-compatible 64-bit
microprocessors with sixth-generation features. The decoupled load/store unit (within the memory management
unit) allows multiple instructions in a single clock cycle. Other features include single-cycle execution, single-cycle
instruction decode, 16KB write-back cache, and clock rates up to 266MHz. These features are possible by the use
of advanced-process technologies and super pipelining.
2.2 DMA CONTROLLER
The equivalent of two 8237A DMA controllers are implemented on the AR-B1570 board. Each controller is a four-
channel DMA device that will generate the memory addresses and control signals necessary to transfer
information directly between a peripheral device and memory. This allows high-speed information transfer with less
CPU intervention. The two DMA controllers are internally cascaded to provide four DMA channels for transfers to
8-bit peripherals (DMA1) and three channels for transfers to 16-bit peripherals (DMA2). DMA2 channel 0 provides
the cascade interconnection between the two DMA devices, thereby maintaining IBM PC/AT compatibility.
The Following is the system information for the DMA channels:
Slave with four 8-bit chnls

2.3 KEYBOARD CONTROLLER
The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives
serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data
in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the
system to poll its status register to determine when data is available.
Data can be written to the keyboard by writing data to the output buffer of the keyboard controller.
Each byte of data is sent to the keyboard controller in a series with an odd parity bit automatically inserted. The
keyboard controller is required to acknowledge all data transmissions. Therefore, another byte of data will not be
sent to keyboard controller until acknowledgment is received for the previous byte sent. The “output buffer full”
interruption may be used for both send and receive routines.
2.4 INTERRUPT CONTROLLER
The equivalent of two 8259 Programmable Interrupt Controllers (PIC) are included on the AR-B1570 board. They
accept requests from peripherals, resolve priorities on pending interrupts in service, issue interrupt requests to the
CPU, and provide vectors which are used as acceptance indices by the CPU to determine which interrupt service
routine to execute. These two controllers are cascaded with the second controller representing IRQ8 to IRQ15,
which is rerouted through IRQ2 on the first controller.
The following is the system information of interrupts levels:

2.5 SERIAL PORT
The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are used to convert parallel data to a serial
format on the transmit side and convert serial data to parallel on the receiver side. The serial format, in order of
transmission and reception, is a start bit, followed by five to eight data bits, a parity bit (if programmed) and one,
1.5 (in a five-bit format only) or two stop bits(in a 6,7, or 8-bit format). The ACEs are capable of handling divisors of
1 to 65535, and produce a 16x clock for driving the internal transmitter logic.
Provisions are also included to use this 16x clock to drive the receiver logic. Also included in the ACE a completed
MODEM control capability, and a processor interrupt system that may be software tailored to the computing time
required to handle the communications link.

Bit 7: This signal may become active during data entry, when the printer is off-line during printing, or when the
print head is changing position or in an error state. When Bit 7 is active, the printer is busy and cannot
accept data.
Bit 6: This bit represents the current state of the printer’s ACK signal. A0 means the printer has received the
character and is ready to accept another. Normally, this signal will be active for approximately 5
microseconds before receiving a BUSY message stops.
Bit 5: A1 means the printer has detected the end of the paper.
Bit 4: A1 means the printer is selected.
Bit 3: A0 means the printer has encountered an error condition.

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.

4.3 WATCHDOG TIMER
This section describes the use of Watchdog Timer, including disable, enable, and trigger. AR-B1570 is equipped
with a programmable time-out period watchdog timer that occupies I/O port 214H. 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 IRQ) due to system fails to trigger or disable
watchdog timer before preset timer, times out.

4.3.1 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

Generally, watchdog function would
reset system after 8 seconds
ꢀ
O 214 0H
Disable watchdog function
C:>debug

Generally, watchdog function would
generate IRQ 9 after 8 seconds
ꢀ
O 214 0H

4.3.2 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.
C:>debug

IDE HDD Block Mode
This option allows your hard disk controller to use the fast block mode to transfer data to and from your hard disk
drive (HDD).
Enabled
Disabled
IDE controller uses block mode.
IDE controller uses standard mode.
IDE PIO
IDE hard drive controllers can support up to two separate hard drives. These drives have a master/slave
relationship, which is determined by the cabling configuration used to attach them to the controller. Your system
supports one IDE controller – a primary and a secondary – so you have the ability to install up to four separate
hard disks.
PIO means Programmed Input/Output. Rather than have the BIOS issue a series of commands effect a
transferring to or from the disk drive, PIO allows the BIOS to tell the controller what it wants and then let the
controller and the CPU perform the complete task by them. This is simpler and more efficient (and faster). Your
system supports five modes, numbered from 0 to 4, which primarily differ in timing. When Auto is selected, the
BIOS will select the best available mode.
KBC input clock
This item it to chose the input clock of Keyboard Controller
OnBoard Serial Port 1 & 2
