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). • 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. 4 AR-B1565/1565A User!s Guide 1.

SYSTEM CONTROLLER This chapter describes the main structure of the AR-B1565/1565A CPU board. The topics are covered as follow: ! Microprocessors ! DMA Controller ! Keyboard Controller ! Interrupt Controller ! Serial Port ! Parallel Port 2.1 MICROPROCESSOR The AR-B1565/1565A uses the NS GEODE GX1 CPU; it is an advanced 32-bit x86 compatible processor offering high performance, with fully accelerated 2D graphics, a 64-synchronous DRAM controller and a PCI bus controller, all on a single chip. This latest generation of the Media GX processor enables a new class of premium performance notebook/desktop, and IPC computer designs. The Media GX MMX with enhanced processor companion chips not only provide advanced video and audio functions but also 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 Media GX family, offering high performance; with 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 Media GX 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 is AC97 Version 2.0 audio compliant that provides an Ultra DMA/33 interface, MPEG2 assist. In addition to the advanced CPU features, the Media GX processor integrates a host of functions in which typically implemented with external components. A full-function graphics accelerator provides pixel processing and rendering functions. The NS Media GX 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 300MHz. 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-B1565/1565A board. Each controller is a four-channel DMA device that will generate the memory addresses and willcontrol 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 to transfer to 8- bit peripherals (DMA1) and three channels to 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 channels Master with three 16-bit channels DMA Controller 1 DMA Controller 2 Channel 0: Spare Channel 4(0): Cascade for controller 1 Channel 1: IBM SDLC Channel 5(1): Spare Channel 2: Diskette adapter Channel 6(2): Spare Channel 3: Spare Channel 7(3): Spare DMA Channel Controller 7 AR-B1565/1565A 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-B1565/1565A 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 interruption levels: Interrupt Level Description NMI Parity check CTRL1 CTRL2 System timer interrupt from timer 8254 IRQ0 keyboard output buffer full IRQ1 Rerouting to IRQ8 to IRQ15 IRQ2 IRQ8:Real time clock IRQ9:Reserved IRQ10:Serial port(depends on setup assignment) IRQ11:Serial port(depends on setup assignment) IRQ12:Reserved for PS/2 mouse IRQ13:Math.Co-processor IRQ14:Hard disk adapter IRQ15:Hard disk adapter IRQ3 Serial port(depends on setup assignment) IRQ4 Serial port(depends on setup assignment) IRQ5 Reserved IRQ6 Reserved for floppy disk adapter IRQ7 Parallel port 1 Interrupt Controller 8 AR-B1565/1565A User!s Guide 2.4.1 I/O Port Address Map Hex Range Device 000-01F DMA controller 1 020-021 Interrupt controller 1 022-023 Cyrix CS5530 040-04F Timer 1 050-05F Timer 2 060-06F 8042 keyboard/controller 070-071 Real-time clock (RTC), non-mask able interrupt (NMI) 080-09F DMA page registers 0A0-0A1 Interrupt controller 2 0C0-0DF DMA controller 2 0F0 Clear Math Co-processor 0F1 Reset Math Co-processor 0F8-0FF Math Co-processor 170-178 Reserved for Fixed disk 1 1F0-1F8 Fixed disk 0 201 Reserved for Game port 208-20A EMS register 0 214 Watch Dog 218-21A EMS register 1 278-27F Parallel printer port (depends on setup assignment) 2E8-2EF Serial port (depends on setup assignment) 2F8-2FF Serial port (depends on setup assignment) 300-31F Prototype card/streaming type adapter 320-33F Reserved 378-37F Parallel printer port (depends on setup assignment) 380-38F SDLC, bisynchronous 3A0-3AF Bisynchronous 3B0-3BF Monochrome display and printer port 3 (LPT 3) 3C0-3CF EGA/VGA adapter 3D0-3DF Color/graphics monitor adapter 3E8-3EF Serial port 3 (depends on setup assignment) 3F0-3F7 Reserved for diskette controller 3F8-3FF Serial port (depends on setup assignment) I/O Port Address Map 9 AR-B1565/1565A User’s Guide 2.4.2 Real-Time Clock and Non-Volatile RAM The AR-B1565/1565A contains a real-time clock compartment that maintains the date and time in addition to storing configuration information about the computer system. It contains 14 bytes of clock and control registers and 114 bytes of general purpose RAM. Because of the use of CMOS technology, it consumes very little power that can be maintained for long periods of time using an internal Lithium battery. The contents of each byte in the CMOS RAM are listed as follows: Address Description 00 Seconds 01 Second alarm 02 Minutes 03 Minute alarm 04 Hours 05 Hour alarm 06 Day of week 07 Date of month 08 Month 09 Year 0A Status register A 0B Status register B 0C Status register C 0D Status register D 0E Diagnostic status byte 0F Shutdown status byte 10 Diskette drive type byte, drive A and B 11 Fixed disk type byte, drive C 12 Fixed disk type byte, drive D 13 Reserved 14 Equipment byte 15 Low base memory byte 16 High base memory byte 17 Low expansion memory byte 18 High expansion memory byte 19-2D Reserved 2E-2F 2-byte CMOS checksum 30 Low actual expansion memory byte 31 High actual expansion memory byte 32 Date century byte 33 Information flags (set during power on) 34-7F Reserved for system BIOS Real-Time Clock & Non-Volatile RAM 2.4.3 Timer The AR-B1565/1565A provides three programmable timers, each with a timing frequency of 1.19 MHz. Timer 0 The output of this timer is tied to interrupt request 0. (IRQ 0) Timer 1 This timer is used to trigger memory refresh cycles. Timer 2 This timer provides the speaker tone. Application programs can load different counts into this timer to generate various sound frequencies. 10 AR-B1565/1565A User!s Guide 2.5 SERIAL PORT The ACEs (Asynchronous Communication Elements ACE1 to ACE4) 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. The serial format, in order to transmission and reception that 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) is a start bit. The ACEs are capable of handling divisors of 1 to 65535, and produce a 16x clock for driving the internal transmitter logic. The provision is not only included the use of this 16x clock to drive the receiver logic. But 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.

(3) Data Swapper The system microprocessor can read the contents of the printer’s Data Latch through the Data Swapper by reading the Data Swapper address. (4) Printer Status Buffer The system microprocessor can read the printer status by reading the address of the Printer Status Buffer. The bit definitions are described as follows: 70 6 5 4 3 2 1 XXX -ERROR SLCT PE -ACK -BUSY Printer Status Buffer NOTE: X presents not used. 13 AR-B1565/1565A User’s Guide 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. (5) Printer Control Latch & Printer Control Swapper The system microprocessor can read the contents of the printer control latch by reading the address of printer control swapper. Bit definitions are as follows: 7 6 5 4 3 2 1 0 X X STROBE AUTO FD XT INIT SLDC IN IRQ ENABLE DIR(write only) Bit’s Definition NOTE: X presents not used. Direction control bit. When logic 1, the output buffers in the parallel port are disabled allowing data driven Bit 5: from external sources to be read; when logic 0, they work as a printer port. This bit is writing only. Bit 4: A1 in this position allows an interrupt to occur when ACK changes from low state to high state. Bit 3: A1 in this bit position selects the printer. Bit 2: A0 starts the printer (50 microseconds pulse, minimum). Bit 1: A1 causes the printer to line-feed after a line is printed. Bit 0: A0.5 microsecond minimum highly active pulse clocks data into the printer. Valid data must be present for a minimum of 0.5 microseconds before and after the strobe pulse. 14 AR-B1565/1565A User!s Guide 3. SETTING UP THE SYSTEM This section describes pin assignments of on board connector and jumper settings. ! Overview ! System Setting 3.1 OVERVIEW AR-B1565/1565A is a Pentium Grade CPU Board, which supports Ethernet, DOC, SSD, and audio card (AR-B9425A) functions. This section provides the hardware’s jumper settings, the connectors’ locations, and the pin assignments. B 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. 15 AR-B1565/1565A User’s Guide 3.2.1 Hard Disk (IDE) Connector (IDE1, IDE2) (1) 40-Pin Hard Disk (IDE) Connector (IDE1) A 40-pin header type connector (IDE1) is provided to interface with up to two embedded hard disk drives (IDE AT bus).

Watchdog Timer will generate a response (system or IRQ) due to system fails to trigger or disable watchdog timer before preset timer, times out. Time Base Enable(D7) Time Factor (D0-D5) Watchdog Register Counter and Write and Compartor Trigger RESET Watchdog Block Diagram 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 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 !

SDRAM Clock Ratio Div By This item is to determine the SDRAM Clock Ratio. 16-Bit I/O Cycle Recovery Time 8-Bit I/O Cycle Recovery Time These options specify the length of the delay (in BUSCLK) inserted between consecutive 8-bit/16-bit I/O operations. USB Controller To enable or disable USB function. 36 AR-B1565/1565A User!s Guide 5.5 PNP/PCI CONFIGURATION PNP/PCI CONFIGURATION PNP OS Installed This item is to choose whether or not installing the PNP (Plug & Play) operation system. Resources Controlled By The available choices are &. To choose the resources will be under the control of system automatically. If is chosen, the following items will be listed. Setting these items one by one will clear up the conflict between NON-PNP ISA extension cards and PNP system. these items are used for the PNP ISA (PCI) cards or NON-PNP old ISA cards which use DMA channel to enable them work normally. Reset Configuration Data This item is used to the function of Reset Configuration Data or not. PCI IRQ Actifed By This item is to determine the active mode. 5.6 LOAD DEFAULT SETTING This section permits the user to select a group of settings for all BIOS Setup options. Not only can you use these items to quickly set system configuration parameters, you can choose a group of settings that have a better chance of working when the system is having configuration related problems. 5.6.1 Load BIOS Defaults User can load the optimal default settings for the BIOS. The uses best-case values that should optimize system performance. If CMOS RAM is corrupted, the optimal settings are loaded automatically. Load high performance settings (Y/N)? 37 AR-B1565/1565A User’s Guide 5.6.2 Load Setup Defaults User can load the Setup option settings by selecting the Fail-Safe item from the Default section of the BIOS Setup main menu. The Fail-Safe settings provide far from optimal system performance, but are the most stable settings. Use this option as a diagnostic aid if the system is behaving erratically. Load failsafe settings (Y/N)? 5.7 INTEGRATED PERIPHERALS This section is designed to configure the peripheral features. Integrated Peripherals 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 to affect a transfer 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 38 AR-B1565/1565A User!s Guide Onboard Serial Port 1,2,3&4 These options are used to select the port address of the on-board serial port A.
