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.

Hardware Installation

3. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

• The GA - 586T2 mainboard.

• USER’ S MANUAL for mainboard.

• Cable set for IDE , Floppy & I/O device.

• Diskette for BUS MASTER ATAPI device (Ver 3.6).

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.

3.4. DRAM INSTALLATION

The mainboard can be installed with 4 / 8 / 16 / 32 MB 72 pins SIMM module
DRAM, and the DRAM speed must be 60 or 70 ns.

The DRAM memory system on mainboard consists of bank 1, & bank 2.
Each bank consists of 2 sockets for 72 pins SIMM module DRAM. Because
the 72 pins SIMM module is 32 bits width, using 2pcs which can match a 64
bits system.

The total memory size is 8 - 256 MB.
For the DRAM installation position, please refer to Figure 3.1. Note that the

Pin 1 of SIMM module must match with the Pin 1 of SIMM socket when the
DRAM SIMM module is installed.

3-5

GA-586T2

Insert the DRAM SIMM module into the SIMM socket at 45 degree angle.
If there is a wrong direction of Pin 1, the DRAM SIMM module couldn't be
inserted into socket completely.

After completely insert SIMM module into socket, then press the SIMM
module in vertical direction until the left and right metal holders can keep the
SIMM module standing up firmly.

Sync. SRAM (Pipeline Burst SRAM)

If Sync SRAM Module is installed, it consists of Pipeline Burst 1 Pcs 64 K x
64 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 SW selection and JP2 to set up the system speed to 60
MHz, 66 MHz or 75 MHz for 3.3V/2.8V Pentium Processor (90-233 MHz) /

•

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.

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

4-9

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

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.

GA-586T2

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.
