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 the computer systems. The charge that can build up in your body may be
more than sufficient to damage integrated circuits on any PC board. T herefore, It is an important to obse rve basic
precautions whenever you use or handle computer components. Although areas with humid clim ates are much
less prone to static build-up, it is always the best to safeguard against ac cidents, which may result in expensive
repairs. The following measures should generally be sufficient to protect your equipment from static discharge:
• Touch a grounded metal object to dischar ge the static electricity in your body (or ideally, wear a groun ded
wrist strap).
• When unpacking and handling the board or other s ystem components, place all materials on an antic static
surface.
• Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom
of every board.

2. SYSTEM CONTROLLER
This chapter describes the major structure of the AR-B9629 CPU board. The following topics are covered:
Microprocessor
DMA Controller
Keyboard Controller
Interrupt Controller
Serial Port (AR-B9449)
Parallel Port (AR-B9449)
2.1 MICROPROCESSOR
The AR-B9629 uses the ALI M6117 CPU; it is designed to perform systems like Intel’s 386SX system with deep
green features.
The 386SX core is the same as M1386SX of Acer Labs. Inc. and 1 0 0 % o b j e ct c o d e c o m pa t i b le w i t h t h e I n t el
38 6S X microprocessor. System manufactur ers can provide 386 CPU based systems optimized for both cost and
size. Instruction pipelining and high bus bandwidth ensure short average instruction execution time and high
system production. Furthermore, it can keep the state internally from charge leakage while external clock to the
core is stopped without storing the data in registers. The power consumption here is almost zero until the clock
stops. The internal structure of this core is 32-bit data and address bus with very lo w supply current. Real mode
as well as Protected mode are available and can run MS-DOS /MS-Windows.
2.2 DMA CONTROLLER
The equivalent of two 8237A DMA controllers are implemented in th e AR-B9629 board. Each controller is a fourchannel DMA device that will generate the memory addresses and will control signals necessary to transfer
info rmat ion d irec tly b etween a peripheral device and memory. This allows high speeding information trans ference w ith
less CPU intervention. The two DMA controllers are internally cascaded to provide four DMA channels for
transferring to 8-bit peripherals (DMA1) and three channels for transferrin g to 16-bit peripherals (DMA2). DMA2
channel 0 provides the cascade interconnection between the t wo DMA devices, thereby maintaining IBM PC/AT
compatibility.
The following is the system information of DMA channels:
DMA Controller 1 DMA Controller 2
Channel 0: Spare Channel 4: Cascade for controller 1
Channel 1: IBM SDLC Channel 5: Spare
Channel 2: Diskette adapter Channel 6: Spare
Channel 3: Spare Channel 7: Spare
Table 2-1 DMA Channel Controller

AR-B9629 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 place d 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 seri es 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-B9629 board. They
accept requests from peripherals, resolve priorities on pending interrupts in service, issue interrupt req uests to the
CPU, and provide vectors which are used as acceptance indices by the CP U to determine which interrupt service
routine to execute.
The following is the system information of interrupts levels:
Interrupt Level Description
NMI Parity check
CTRL1 CTRL2
IRQ 0 System timer interrupt from timer 8254
IRQ 1 Keyboard output buffer full
IRQ 2 Rerouting to IRQ 8 & IRQ 14
IRQ 8: Real time clock

2.5 SERIAL PORT
The ACEs (Asynchronous Communication Elements ACE1 to ACE4) are not only used to convert parallel data to a
serial format on the transmit side but also used to convert serial data to parallel on the receiver side. In order of
transmission and reception, the serial format is a start bit, followed by five to eight data bits, a parity bit (if
programmed) and one, one and half (five-bit format only) or two stop bits. The ACEs are capable of handling
divisors of 1 to 65535, and produce a 16x clock for driving the internal transmitter logic.
Provisions are not only included to use this 16x clock to dr ive the receiver logic b ut also included in the ACE as 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.
The following table is a summary of each ACE accessible register

Page 18
AR-B9629 User’s Guide
3.2 SYSTEM SETTINGS
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 [shorting plug] 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.
We will show the locations of the AR-B9629 jumper pins, and the factory-default settings.
CAUTION: Do not touch any electronic component unless you are safely grounde d. Wear a grounded wrist strap
or touch an exposed metal part of the system unit chassis. The static discharg es from your fin gers c an
permanently damage the electronic components.

4.1 BIOS SETUP OVERVIEW
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 co nsole 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 turned on, the BIOS will perform a diagnostics of the system and will display the size of the
memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the mai n 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 yo u
wish to modify, and then press the [Enter] key to assure the option and configure the functions.

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 AUT OEXEC.BAT file. For information on how to
create this file, please refer to the MS-DOS manual.
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 t ype
using the left-or right-arrow key.
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. F or the master and slave jumpers, please refer to
the hard disk’s installation descriptions and the hard disk jumper settings.
You can select <AUTO> under the <TYPE> and <MODE> fields. This will enable auto detection of your IDE drives
during bootup. 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 abov e by the <USER> option.
Boot Sector Virus Protection
This option protects the boot sector and partition table of your hard dis k 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 inv estigate your system. The
default setting is <Disabled>. This setting is recommended because it conflicts with new operating systems.
Installation of new operating system requires that you disable this to prevent write errors.

These options determine where the system looks first for an operating system. The default setting is to check first
the hard disk and then the floppy drive, and last the CDROM.
BootUp 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 d isk drives in the Swap A, B setting, otherwise
leave on the default 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 conn ectors of the flop p y disk drives. Whe n
the function’s setting is <Enabled>, the BIOS swapped floppy drive assign ments so that Drive A becomes Drive B,
and Drive B becomes Drive 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 bootup.
PS/2 Mouse Support
The setting of Enabled allows the system to detect a PS/2 mouse on bootup. 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.
