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 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.

3. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

• The GA - 586S mainboard.

• USER'S MANUAL.

• Cable set for I/O Device.

• Driver Diskette (optional).

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.

P-100/P-120/P-133) / Cyrix 6x86 (P-120+ / P-150+ / P-133P+ / P-166+/ P-200+) / Cyrix

3-5

Hardware Installation

6x86L (P-150+ / P166+ / P-200+ 2.8V).
The mainboard can use PENTIUM processor, P54CT, P55C or P54CTB, AMDK5, Cyrix

6x86 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(optional)

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

Function Reserved.

3-6

GA-586S

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

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 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

4-8

BIOS Configuration

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 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

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

Appendix A Post Message

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.
