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 - 586S2 mainboard.
• USER’ S MANUAL for mainboard.
• Cable set for IDE & Floppy .
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 damage 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 Chip is installed, it consists of Pipeline Burst 1 Pc 64 K x 64
512KByte.
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 SW selection to set up the system speed to 60 or 66 or 75
MHz for 3.3V/2.5V Pentium Processor (90-233 MHz) / AMDK5(PR133 /
PR166) / AMD-K6(166/180/200(2.9V)/233(3.2V)), Cyrix / IBM 6x86 (PR150+
/ PR166+/ PR200+), Cyrix / IBM 6x86L (PR150+/PR166+/PR200+ (2.8V)),
Cyrix / IBM 6x86MX (PR166 (60x2.5 2.9V) / PR200 (66x2.5 2.9V) (75x2
2.9V)/ PR233 (66x3 2.9V) (75x2.5 2.9V)).
The mainboard can use Pentium Processor, P54CT, MMX or P54CTB,
AMDK5, AMD-K6, Cyrix / IBM 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

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 & KEY LOCK CONNECTOR INSTALLATION
There is a system power LED light and a key on the panel of case. The
power LED will light on when system is powered-on, and the key can lock or
unlock the keyboard input, both are connected to a 5 PIN connector. 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.
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 60 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.

Page 53
Specification
3.13. GREEN FUNCTION INSTALLATION
There are two jumpers for the purpose of power saving, GN and GD, to
indicate the power saving function . The GD is a indicator (green LED) for
green function. If the green LED is OFF, the system is in normal operation. If
the green LED is blinking, the system is in green mode. The GN switch will
force the system into green mode .
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

Memory
4-8
Page 63
GA-586S2
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.
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, 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 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 to 1024 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
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.
A-1
Page 96
Appendix A: Post Message
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.
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.
A-2
Page 97
GA-586S2
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.
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 ISA 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 program the memory correctly.
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 key is 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.
A-3
Page 98
Appendix A: Post Message
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
field.
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-miscible 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 ISA 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.
A-4
Page 99
GA-586S2
Ö Should Have ISA 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.
F
When this error appears, the system will boot in ISA mode, which allows
