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. It is, therefore, important to observe basic precautions whenever you use or handle co mputer components. Although areas with humid climates are much less prone to static build-up, it is always the best to safeguard against accidents which may result in e xpensive 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-B9622 CPU board. The following topics are covered:

 Microprocessor  DMA Controller  Keyboard Controller  Interrupt Controller  Serial Port  Parallel Port

2.1 MICROPROCESSOR

The AR-B9622 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 mp a t ib l e w i th t h e I n t e l 38 6S X microprocessor. System manuf acturers 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 throughput. 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-B9622 board. Each controller is a fourchannel DMA device that will generate the memory addresses and control signals necessary to transfer info r mati o n dir ectl y bet ween a peripheral device and memory. This allows high speeding information trans f er wi t h less CPU intervention. The two DMA controllers are internally cascaded to pr ovide 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 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-B9622 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-B9622 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 interrupt levels:

InInterrupt Level

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 rec eiver 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, 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 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.

The following table is a summary of each ACE accessible register

3.1 OVERVIEW

The AR-B9622 is an all-in-one, half-size, 386SX CPU board. This section provi des hardware jumper settings, the connectors’ locations, and the pin assignment.

CAUTION: The CPU board doesn’t support the SIMM-type DRAM.

AR-B9622 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-B9622 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.

5.3 WATCHDOG TIMER

This section describes how to use the Watchdog Timer, disabled, enabled, and trigger. The AR-B9622 is equipped with a programmable time-out period watchdog timer. User can use the program to

enable the watchdog timer. Once you have enabled the watchd og timer, the program should trigger it every time before it times out. If your program fails to trigger or disable this timer before it times out because of system hangup, it will generate a reset signal to reset the system. The time-out period can be programmed to be 30.5μ

seconds to 512 seconds.

5.3.1 Watchdog Timer Setting

The watchdog timer is a circuit that may be used from your program software to detect crashes or hang-ups. The watchdog timer is automatically disabled after reset.

Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time before it times-out. After you trigger the watchdog timer, it will be set to zero and start to count again. If your pro gram fails to trigger the watchdog timer before time-out, it will generate a reset pulse to reset the system or trigger the IRQ15 signal to tell your program that the watchdog is times out.

If you want to generate IRQ15 signal to warn your program when watchdog times out, the following table listed the relation of timer factors between time-out period. And if you use the IRQ15 signal to warn your program when watchdog timer out, please enter the BIOS Setup the <Peripheral Setup> menu, the <OnBoard PCI IDE> and <IDE Prefetch> these two items must set to Primary.

NOTE: 1. If you program the watchdog to generate IRQ15 signal when it times out, you should initial IRQ15

interrupt vector and enable the second interrupt controller (8259 PIC) in order to enable CPU to process this interrupt. An interrupt service routine is required too.

2. Before you initial the interrupt vector of IRQ15 and enable the PIC, please enable the watchdog timer previously, otherwise the watchdog timer will generate an interrupt at the time watchdog timer is en abled .

6.1 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 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 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, the n you must configure the hard disk drive in the standard method as described above 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.
