PCI - ISA SOLUTION

PENTIUM PCI - ISA BUS MAINBOARD

REV.2.0 Second Edition

GA-586VX

Who need 82430 VX?

1. If you want to get the best performance.
(Because more buffers & Quick DRAM Timing is supported.)

2. If you need a USB ports for C&C application.
(Because 2 USB ports will be ready in the end of Q2/96".)

Why do you need GA-586VX 82430VX motherboard?

1. Because it is the best performance motherboard. (See next page) We have
compared GA-586VX with PC Magazine EDITOR choice-system.

2. Because GA-586VX has 2 banks Sync. DIMM Module, you may upgrade
your memory easily with flexibility.

Others don't, because they only have 1 bank Sync. DIMM Module.

3. Just plug a 256KB Pipeline cache module, and you can get cache size upto
512KB easily. No jumper setting needed.

Others don't, because they don't have an upgrade cache module. Or they
have to change jumper setting to 512KB.

4. No risk for Intel P55CT CPU upgrade because GA-586VX will auto detect
P55CT and support right operation voltage.

Others don't, because they need an EXTRA VRM module or jumper setting
for P55CT CPU upgrade.

5. DIP switch setting is supported. You don't have to worry any jumper shunter
missed.

Others don't, because they have jumpers on board.

Introduction

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 bandwidth-constrained 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.

3. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

• The GA - 586VX mainboard.

• USER'S MANUAL.

• Cable set for I/O Device.

• Diskette for BUS Master IDE Driver.

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 mainboard. 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.

3.5. SRAM INSTALLATION

Sync. SRAM (PipeLine Burst SRAM)

If Sync SRAM Module is installed, it consists of Pipeline Burst 2 PCs 32 K x 32
from 256K upgradable to 512K.

There is no jumper for cache size setting.

3.6. CPU INSTALLATION AND JUMPERS SETUP

The system speed depends on the frequency of CLOCK GENERATOR. The
user can change SW1 selection to set up the system speed to 50 MHz, 60
MHz or 66 MHz for 3.3V/2.5V Pentium Processor (75-200 MHz)/AMDK5(P­75/P-90/P-100/P-120/P-133/P-166/P-200)/Cyrix 6x86 (P-120+/P-133/P­150+/P-166+), Cyrix 6x86L(P-150+/P-166+ 2.8V).
The mainboard can use PENTIUM processor, P54CT, P55C or P54CTB,
AMDK5, Cyrix6x86 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 faster than CPU's.

M

The CPU is a sensitive electric component and it can be easily damaged by
static electricity, so users must keep it away from metal surface when the
CPU is installed onto mainboard.

M

When the user installs the CPU on socket, please notice that 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 fact that the life-time of RTC internal battery is 5 years, the user can
change a new RTC to replace old one after it does not work. The new one's
brand and type must be same with the old one.

3.8. SPEAKER CONNECTOR INSTALLATION

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

3.9. POWER LED CONNECTOR INSTALLATION

There is a system power LED light on the panel of case. The power LED will
light on when system is powered-on. The connector should be installed to

PWR of mainboard in correct direction.

3.10. TURBO SWITCH CONNECTOR INSTALLATION

The TURBO switch on the panel is used for controlling the system speed.

3-6

GA-586VX

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 50 MHz speed method to implement
TURBO switching function. The TB 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

Please don't use switch ON/OFF when power is ON.

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 TD 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 RST on mainboard.

3.13. GREEN FUNCTION INSTALLATION

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

3.14. PERIPHERAL DEVICE INSTALLATION

After installation of the device and setup of the jumpers, the mainboard can be
mounted into the case and fixed by screw. To complete the mainboard
installation, the peripheral devices could be installed now. The basic system
needs a display interface card and a storage device.
If a PCI - Bus device is to be installed in the system, any one of four PCI - Bus
slots can be used for Slave or Master PCI - Bus device.
After installing the peripheral device, the user should check everything again
and prepare to power-on the system.

3.15. KEYBOARD SETTING FUNCTION

After booting the O.S., there are some special functions used by keyboard as
follows:
"CTRL_ALT_DEL" − Pressing these keys simultaneously will cause

system to Warm Start (Software Reset).

3-7

GA-586VX

4. BIOS CONFIGURATION

monitor that must match your video display card and monitor. Although

4-5

BIOS Configuration

secondary monitors are supported, you do not have to select the type in
setup.

EGA/VGA Enhanced Graphics Adapter/Video Graphics Array. For

EGA, VGA, SVGA, or PGA monitor adapters
CGA 40 Color Graphics Adapter, power up in 40 column mode
CGA 80 Color Graphics Adapter, power up in 80 column mode
MONO Monochrome adapter, includes high resolution

monochrome adapters

• Halt on

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

NO errors The system boot will not be stopped for any error

that may be detected

All errors Whenever the BIOS detects a non-fatal error the

system will be stopped and you will be prompted

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 Kfor systems with 512K memory
installed on the motherboard, or 640K for systems with 640K or
more memory installed on the motherboard.

Extended Memory

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

Expanded Memory

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

4-6

GA-586VX

usually 64K within 1MB or memory above 1MB, depending 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 640K 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 usage 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-586VX

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 corrupted or the slot has been 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 corrupted. 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-586VX

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, which will enable the NMI.

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

PLEASE RUN EISA CONFIGURATION UTILITY
The board ID does not match the ID stored in the EISA non-volatile

memory.

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

you to run the EISA Configuration Utility.
