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. SYSTEM CONTROLLER
This chapter describes the main structure of the AR-B1570 CPU board. The following topics are covered:
! Microprocessors
! DMA Controller
! Keyboard Controller
! Interrupt Controller
! Serial Port
! Parallel Port
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 fourchannel 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:

AR-B1570 User’s Guide
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.

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.

AR-B1570 User’s Guide
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
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 214 C8H
Generally, watchdog function would reset system after 8 seconds
! O 214 0H
Disable watchdog function
C:>debug
! O 214 88H
Generally, watchdog function would generate IRQ 9 after 8 seconds
! O 214 0H
Disable watchdog function
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
! O 214 CFH
Generally, watchdog function would reset system after 15 seconds
! O 214 40H
Disable watchdog function
Trigger success.

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 IDE controller uses block mode.
Disabled 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
These options are used to select the port address of the on-board serial port A. The options are 3F8H, 2F8H,
3E8H, 2E8H, Auto and Disable. Port 1 is COM A; Port 2 is Com D and so on. Port four can be set to be IrDA
(Choose Auto) if the IrDA device has been connected.
OnBoard Parallel Port
This option is used to select the port address of the on-board parallel port. The options are 378H, 278H, 3BCH, and Disabled.

This BIOS Setup has an optional password feature. The system can be configured so that all users must enter a password every time the system boots or when BIOS Setup is executed.
5.8.1 Setting Password
Select the appropriate password icon from the Security section of the BIOS Setup main menu. Enter the password and press [Enter]. The screen does not display the characters entered. After the new password is entered, retype the new password as prompted and press [Enter].
If the password confirmation is incorrect, an error message appears. If the new password is entered without error, press [Esc] to return to the BIOS Main Menu. The password is stored in CMOS RAM after BIOS is completed.
The next time the system boots, the prompt for the password function is present and is enabled.
Enter new supervisor password:
5.8.2 Password Checking
The password check option is enabled in Advanced Setup by choosing either Always (the password prompt appears every time the system is powered on) or Setup (the password prompt appears only when BIOS is run).
The password is stored in CMOS RAM. User can enter a password by typing with the keyboard. Enter a 1-6 character password. The password does not appear on the screen when typed. Make sure you write it down.
5.9 IDE HDD AUTO DETECTION
This option detects the parameters of an IDE hard disk drive, and automatically enters them into the Standard
CMOS Setup screen.
5.10 BIOS EXIT
This section is used to exit the BIOS main menu in two types of situation. After making your changes, you can either save them or exit the BIOS menu and without saving the new values.
5.10.1 Save & Exit Setup
This item set in the <Standard CMOS Setup>, <BIOS Features Setup>, <Chipset Features Setup>, <Power
Management Setup>, <Integrated Peripherals> and the new password (if it has been changed) will be stored in the
