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.

3. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

l The GA - 586IP mainboard.

l USER'S MANUAL.

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.

Hardware Installation

The DRAM installation position refer to Figure 3.1, and notice the Pin 1 of SIMM module
must match with the Pin 1 of SIMM socket when the DRAM SIMM module is installed.

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 con­firmly.

3.5. SRAM INSTALLATION AND JUMPERS SETUP

The cache memory system consists of SRAM, the SRAM type is 3.3V 32Kx8-15 ns, 64Kx8­15 ns or 128Kx8-15 ns.

The mainboard can be installed 256 KB or 512 KB cache memory when using 32Kx8 or
64Kx8 (128Kx8) type DATA SRAM separately. Please refer to the following table to install
cache memory system :

SIZE TYPE J15
256 KB 32 K x 8 1 - 2
512 KB 64 K x 8 or 128 K x 8 2 - 3

Because there are not standard IC's coding number of SRAM, refer to the following table to
identify the SRAM component:

32 K x 8 64 K x 8 128 K x 8
W24257AK-15 W24512AK-15 W241024AK-15
UM61256-15 AS7C512-15 AS7C1024-15
71256-15

3.6. CPU INSTALLATION AND JUMPERS SETUP

The system's speed depends on the frequency of CLOCK GENERATOR. The user can
change the JUMPER (J19) selection to set up the system speed to 60 MHz or 66 MHz for 60
or 66 MHz PENTIUM CPU.

The mainboard can use 3.3V 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.

J19 CPU Type CLK. GEN. Speed CPU Speed

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.

_____________________________________________________________16

Hardware Installation

________________________________________________________________

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 REAL-TIME 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 J14 is
used to connect speaker. The speaker can work well in both direction of connector when it is
installed to the connector J14 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 J9
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.

Because a PENTIUM cannot accept real clock speed change when program is executed, so

________________________________________________________________

17

GA-586IP

_____________________________________________________________

the mainboard uses simulation method to implement TURBO switching function. The J12 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 J13 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 J8 on mainboard.

3.13. 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 control interface
card.

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.

After installing the peripheral device, the user should check everything again, and prepare to
power-on the system.

• Drive C type / Drive D type

The category identify the types of hard disk drive C or drive D that has been installed in the computer. There are 46
pre-defined types and a user definable type. Type 1 to Type 46 are pre-defined. Type User is user-definable.

Press PgUp or PgDn to select a numbered hard disk type or type the number and press <Enter>. Note that the
specifications of your drive must match with the drive table. The hard disk will not work properly if you enter improper
information for this category. If your hard disk drive type is not matched or listed, you can use Type User to define
your own drive type manually.

If you select Type User, related information is asked to be entered to the following items. Enter the information directly
from the keyboard and press <Enter>. Those information should be provided in the documentation form your hard
disk vendor or the system manufacturer.

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.

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

________________________________________________________________

25

GA-586IP

_____________________________________________________________

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

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.

l 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.

l 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.

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.

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.

_____________________________________________________________46

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.

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.

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.

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

the EISA Configuration Utility.
