1.5. INTRODUCE THE PCI - BUS

Connecting devices to a CPU local bus can dramatically increase the speed
of I/O-bound peripherals with only a slight increase in cost over traditional
systems. This price / performance point has created a vast market potential
for local bus products. The main barrier to this market has been the lack of
an accepted standard for local bus peripherals. Many mainboard and chipset
manufactures developed their own local bus implementations, but they are
incompatible with each other. The VL (Video Electronics Standards
Association) local bus and PCI (Peripheral Component Interconnect) bus
specification was created to end this confusion.

The PCI - bus standard, under development since Jun. 1992, which is
designed to bring workstation-level performance to standard PC platform.
The PCI - bus removes many of the bottlenecks that have hampered PC for
several years. On the PCI - bus, peripherals operate at the native speed of
the computer system, thus enabling data transfer between peripherals and
the system at maximum speed. This performance is critical for bandwidth­constrained devices such as video, multimedia, mass storage, and
networking adapters.

PCI - bus standard provides end-users with a low-cost, extendible and
portable local bus design, which will allow system and peripherals from
different manufactures to work together.

1.6. FEATURES

q 32 bits bus transfer mode.

q Bus Master or Slave access.

q Memory burst transfer to 132 MB/sec.

q 33 MHz operation speed.

q 10 device loading ability.

q CPU independent.

3. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

• The GA - 586AP mainboard.

• Diskette for Enhanced IDE Device Driver ( 1 x 1.44MB Diskette).

• USER'S MANUAL.

• Cable set for I/O Device.

The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packing until it is installed.

Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the
same point as the anti-static mat.

Inspect the mainboard carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there are no shipping and
handling damages on the board before proceeding.

After opening the mainboard carton, extract the system board and place it
only on a grounded anti-static surface component side up. Again inspect the
board for damage. Press down on all of the socket IC's to make sure that
they are properly seated. Do this only on with the board placed on a firm flat
surface.

M

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED.

You are now ready to install your maniboard. The mounting hole pattern on
the mainboard matches the IBM-AT system board. It is assumed that the
chassis is designed for a standard IBM XT/AT mainboard mounting.

Place the chassis on the anti-static mat and remove the cover. Take the
plastic clips, Nylon stand-off and screws for mounting the system board, and
keep them separate.

3.6. CPU INSTALLATION AND JUMPERS SETUP

The system's speed depends on the frequency of CLOCK GENERATOR.
The user can change the JUMPER (JP10, JP11) selection to set up the
system speed to 50 MHz, 60 MHz or 66 MHz for 75 MHz, 90 MHz or 100
MHz 3.3 V PENTIUM processor.

The mainboard can use PENTIUM or P54CT CPU, and the CPU speed
must match with the frequency of CLOCK GEN. It will cause system hanging
up if the CLOCK GEN.'S frequency is higher than CPU's.

M

When the user installs the CPU on socket, please notice the PIN 1
of CPU is in the same corner as the PIN 1 of socket!

M

Before the CPU is installed, the mainboard must be placed on a flat
plane in order to avoid being broken by the pressure of CPU
installation.

3.7. CMOS RTC & ISA CFG CMOS SRAM

There're RTC & CMOS SRAM on board, they have a power supply from
internal battery to keep the DATA inviolate & effective. The RTC is a REAL­TIME CLOCK device which provides the DATE & TIME to system. The
CMOS SRAM is used for keeping the information of ISA device system
configuration, so the system can automatically boot OS. every time.

Due to the life-time of RTC internal battery is 10 years, the user can change
a new RTC to replace old one after it can not work. The new one's brand and
type must be same with old one.

3.8. SPEAKER CONNECTOR INSTALLATION

There is always a speaker in AT system for sound purpose. The 4 - Pins
connector JP17 is used to connect speaker. The speaker can work well in
both direction of connector when it is installed to the connector JP17 on
mainboard.

3.9. POWER LED & KEY LOCK CONNECTOR INSTALLATION

There are a system power LED lamp and a key on the panel of case. The
power LED will light on when system is powered-on, and the key can lock the
keyboard input or unlock it, both of them are connected to a 5 PIN connector.
The connector should be installed to JP18 of mainboard in correct

direction.

Hardware Installation

3.10. TURBO SWITCH CONNECTOR INSTALLATION

The TURBO switch on the panel is used for controlling the system speed.
Some program developed on XT should be executed with a low speed
system, so a high speed system needs the speed switching function to
change its running speed.

The mainboard uses helf speed method to implement TURBO switching
function. The JP15 on mainboard should be connected to the TURBO switch
on panel, and user can push in or pop out the TURBO switch to enable or
disable the turbo function of system.

M

If not necessary, please don't use De-turbo mode. (always keep
system in Turbo mode)

3.11. TURBO LED CONNECTOR INSTALLATION

The TURBO LED on panel can indicate the current speed status of system.
The TURBO LED connector should be installed to JP16 in correct direction.

3.12. HARDWARE RESET SWITCH CONNECTOR INSTALLATION

The RESET switch on panel provides users with HARDWARE RESET
function which is almost the same as power-on/off. The system will do a cold
start after the RESET switch is pushed and released by user. The RESET
switch is a 2 PIN connector and should be installed to JP14 on mainboard.

3.13. GREEN FUNCTION INSTALLATION

For the purpose of power saving, there are two jumpers, JP13 and JP12, to
make sure the power saving function doing well. The JP13 is a indicator
(green LED) for green function. If the green LED is ON, the system is
operating in green mode. The JP12 is a switch to force the system get
into green mode immediately.

3.14. PERIPHERAL DEVICE INSTALLATION

After the device installation and jumpers setup, the mainboard can be
mounted into the case and fixed by screw. To complete the mainboard
installation, the peripheral device could be installed now. The basic system
needs a display interface card and a disk device.

If the PCI - Bus device is to be installed in the system, any one of three PCI ­Bus slots can be used no matter Slave or Master PCI - Bus device being
installed.

• Halt on

The category determines whether the computer will stop if an error is
detected during power up.

NO errors Whenever the BIOS detects a non-fatal error the

system will be stopped and you will be prompted

All errors The system boot will not be stopped for any error

that may be detected

All,But Keyboard The system boot will not stop for a keyboard

error; it will stop for all other errors

All, But Diskette The system boot will not stop for a disk error; it

will stop for all other errors

All, But Disk/Key The system boot will not stop for a keyboard or

disk error; it will stop for all other errors

• Memory

The category is display-only which is determined by POST (Power On
Self Test) of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of base (or
conventional) memory installed in the system. The value of the
base memory is typically 512 K for systems with 512 K memory
installed on the motherboard, or 640 K for systems with 640 K
or more memory installed on the motherboard.

______________________________________________________________________

BIOS Configuration

Extended Memory

The BIOS determines how much extended memory is present
during the POST. This is the amount of memory located above
1 MB in the CPU's memory address map.

Expanded Memory

Expanded Memory in memory defined by the
Lotus/Intel/Microsoft (LIM) standard as EMS. Many standard
DOS applications can not utilize memory above 640 K, the
Expanded Memory Specification (EMS) swaps memory which
not utilized by DOS with a section, or frame, so these
applications can access all of the system memory. Memory can
be swapped by EMS is usually 64 K within 1 MB or memory
above 1 MB, depends on the chipset design.

Expanded memory device driver is required to use memory as
Expanded Memory.

Other Memory

This refers to the memory located in the 640 K to 1024 K
address space. This is memory that can be used for different
applications. DOS uses this area to load device drivers to keep
as much base memory free for application programs. Most use
for this area is Shadow RAM.

Appendix A: Post Message

APPENDIX A: POST MESSAGE

When the BIOS encounters an error that requires the user to correct
something, either a beep code will sound or a message will be displayed in a
box in the middle of the screen and the message PRESS F1 TO CONTINUE,
CTRL-ALT-ESC OR DEL TO ENTER SETUP will be shown in the
information box at the bottom.

• POST BEEP

Currently there is only one beep code in BIOS. This code indicates that
a video error has occurred and the BIOS cannot initialize the video
screen to display any additional information. This beep code consists of
a single long beep followed by two short beeps.

• ERROR MESSAGE

Once or more of the following messages may be displayed if the BIOS
detects an error during the POST. This list includes message for both
the ISA and the EISA BIOS.

Ö CMOS BATTERY HAS FAILED

CMOS battery is no longer functional. It should be replaced.

Ö CMOS CHECKSUM ERROR

Checksum of CMOS is incorrect. This can indicate that CMOS has
become corrupt. This error may have been caused by a weak battery.
Check the battery and replace if necessary.

Ö DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

No boot device was found. Insert a system disk into Drive A: and press
<Enter>. If you assumed the system would boot from the hard drive,
make sure the controller is inserted correctly and all cables are properly
attached. Also be sure the disk is formatted as a boot device. Then
reboot the system.

Ö DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP

Type of diskette drive installed in the system is different from the CMOS
definition. Run Setup to re-configure the drive type correctly.

______________________________________________________________________

A-1

GA-586AP
______________________________________________________________________

Ö DISPLAY SWITCH IS SET INCORRECTLY

Display switch on the motherboard can be set to either monochrome or
color. This indicates the switch is set to a different setting than indicated
in Setup. Determine which setting is correct, and then either turn off the
system and change the jumper, or enter Setup and change the VIDEO
selection.

Ö DISPLAY TYPE HAS CHANGED SINCE LAST BOOT

Since last powering off the system, the display adapter has been
changed. You must configure the system for the new display type.

Ö EISA Configuration Checksum Error

PLEASE RUN EISA CONFIGURATION UTILITY
The EISA non-volatile RAM checksum is incorrect or cannot correctly

read the EISA slot. This can indicate either the EISA non-volatile
memory has become corrupt or the slot has configured incorrectly. Also
be sure the card is installed firmly in the slot.

Ö EISA Configuration Is Not Complete

PLEASE RUN EISA CONFIGURATION UTILITY
The slot configuration information stored in the EISA non-volatile

memory is incomplete.

F When either of these errors appear, the system will boot in ISA mode,

which allows you to run the EISA Configuration Utility.

Ö ERROR ENCOUNTERED INITIALIZING HARD DRIVE

Hard drive cannot be initialized. Be sure the adapter is installed correctly
and all cables are correctly and firmly attached. Also be sure the correct
hard drive type is selected in Setup.

Ö ERROR INITIALIZING HARD DISK CONTROLLER

Cannot initialize controller. Make sure the cord is correctly and firmly
installed in the bus. Be sure the correct hard drive type is selected in
Setup. Also check to see if any jumper needs to be set correctly in the
hard drive.

A-2

______________________________________________________________________

Appendix A: Post Message

Ö FLOPPY DISK CNTRLR ERROR OR NO CNTRLR PRESENT

Cannot find or initialize the floppy drive controller. Make sure the
controller is installed correctly and firmly. If there are no floppy drives
installed, be sure the Diskette Drive selection in Setup is set to NONE.

Ö Invalid EISA Configuration

PLEASE RUN EISA CONFIGURATION UTILITY
The non-volatile memory containing EISA configuration information was

programmed incorrectly or has become corrupt. Re-run EISA
configuration utility to correctly program the memory.

F When this error appears, the system will boot in ISA mode, which allows

you to run the EISA Configuration Utility.

Ö KEYBOARD ERROR OR NO KEYBOARD PRESENT

Cannot initialize the keyboard. Make sure the keyboard is attached
correctly and no keys are being pressed during the boot.

If you are purposely configuring the system without a keyboard, set the
error halt condition in Setup to HALT ON ALL, BUT KEYBOARD. This
will cause the BIOS to ignore the missing keyboard and continue the
boot.

Ö Memory Address Error at ...

Indicates a memory address error at a specific location. You can use
this location along with the memory map for your system to find and
replace the bad memory chips.

Ö Memory parity Error at ...

Indicates a memory parity error at a specific location. You can use this
location along with the memory map for your system to find and replace
the bad memory chips.

Ö MEMORY SIZE HAS CHANGED SINCE LAST BOOT

Memory has been added or removed since the last boot. In EISA mode
use Configuration Utility to re-configure the memory configuration. In
ISA mode enter Setup and enter the new memory size in the memory
fields.

______________________________________________________________________

A-3

GA-586AP
______________________________________________________________________

Ö Memory Verify Error at ...

Indicates an error verifying a value already written to memory. Use the
location along with your system's memory map to locate the bad chip.

Ö OFFENDING ADDRESS NOT FOUND

This message is used in conjunction with the I/O CHANNEL CHECK and
RAM PARITY ERROR messages when the segment that has caused the
problem cannot be isolated.

Ö OFFENDING SEGMENT:

This message is used in conjunction with the I/O CHANNEL CHECK and
RAM PARITY ERROR messages when the segment that has caused the
problem has been isolated.

Ö PRESS A KEY TO REBOOT

This will be displayed at the bottom screen when an error occurs that
requires you to reboot. Press any key and the system will reboot.

Ö PRESS F1 TO DISABLE NMI, F2 TO REBOOT

When BIOS detects a Non-maskable Interrupt condition during boot, this
will allow you to disable the NMI and continue to boot, or you can reboot
the system will the NMI enabled.

Ö RAM PARITY ERROR - CHECKING FOR SEGMENT ...

Indicates a parity error in Random Access Memory.

Ö Should Be Empty But EISA Board Found

PLEASE RUN EISA CONFIGURATION UTILITY
A valid board ID was found in a slot that was configured as having no

board ID.

F When this error appears, the system will boot in ISA mode, which allows

you to run the EISA Configuration Utility.

Ö Should Have EISA Board But Not Found

PLEASE RUN EISA CONFIGURATION UTILITY
The board installed is not responding to the ID request, or no board ID

has been found in the indicated slot.

______________________________________________________________________

A-4

______________________________________________________________________

Appendix A: Post Message

F When this error appears, the system will boot in ISA mode, which allows

you to run the EISA Configuration Utility.

Ö Slot Not Empty

Indicates that a slot designated as empty by the EISA Configuration
Utility actually contains a board.

F When this error appears, the system will boot in ISA mode, which allows

you to run the EISA Configuration Utility.

Ö SYSTEM HALTED, (CTRL-ALT-DEL) TO REBOOT ...

Indicates the present boot attempt has been aborted and the system
must be rebooted. Press and hold down the CTRL and ALT keys and
press DEL.

Ö Wrong Board In Slot
