USER'S MANUAL

1. System power on by PS/2 Mouse: First, enable this function
in CMOS Set up, then y ou can power on the system by double
clicking the right or left button of your PS/2 Mouse.

2. System power on by Keyboard: If your ATX power supply
supports larger than 300 mA 5V Stand-By current, you can
power on your system by entering password from the
Keyboard after setting the “Key board power on” jumper (JP1)
and password in CMOS Setup.

3. Support Modem Ring-On. (Include internal Modem and
external modem on COM A and COM B)

4. Wake-up on LAN supports(on J7
must support larger than 720 mA 5V Stand-By curr en t.

5. Support 3 steps ACPI LED.

Quick Installation Guide

I. Quick Installation Guide :
CPU SPEED SETUP

The system bus fr equency can be switched at 66MHz, 100MHz and 133 MHz by
adjusting DIP SW2. The CPU frequen cy ratio can be switched from X3 to X 9.5
by adjusting DIP SW1. The user can set up CPU speed for 300-733MHz
processors by adjusting SW1 and SW2 properly.

The CPU speed must match with the frequency RATIO. It will cause

0000

system han g ing up if the frequency RATIO is higher than CPU's.

Note: Please set the CPU host frequency in accordance with your
processor’s specificat ions. We don’t recommend you to set the
system bus frequency over the CPU’s spe c ification because
these specific bus frequencies are not the standar d
specifications for CP U, chipset and most of the peripherals.
Whether your system can run under these specific bus
frequencies properly will depend on your hardware
configurations, including CPU, Chipsets, SDRAM,
Cards….etc.

1.6 What is AGP

The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI br idge
device that supports an AG P port. The main purpose of the AGP port is to
provide fast access to system memory.

????

The AGP po rt c an b e u sed eit her a s f ast P CI po rt (32- bits at 66M Hz v s. 32-bi ts
at 33MHz) or as an AGP port which supports 2x data-rate, a read queue, and
side band addressing. When the 2x-data rate is used the port can tr ansmit data
at 533MB/sec (66.6*2*4). The read-queue can be used to pipeline reads –
removing the effects of the reads-la tency. Side band addressing can be used to
transmit the data address on a separate line in order to speed up the
transaction.

The

•

USER'S MANUAL for main board.

•

Cable set for IDE, Floppy & I/O devices.

•

CD for main board Utilities.

The main board contains sensitive electric components, which can be easily
damaged by static electricity, so the main board 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 main board carton for o bvious da mage. Shipping and handli ng may
cause damage to your board. Be sure there are no shipping and handling
damages on the board before proceeding.

main board.

After opening the main board carton, ex tract the system board and place it only
on a grounded anti-static sur face 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 fl at surface.

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED.

3.4. DRAM INSTALLATION

The main board can be installed with 16 / 32 / 64 / 128 / 256 / 512 MB(256Mb
technology) 168 pins DIMM module DRAM. When system bus speed is set to
100MHz, 100MHz SDRAM is required. The DRAM memory system on main
board consists of bank 0, 1& bank 2.

3-5

6VA7+

Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM
module may match a 64 bit s system. The total memory size is 16 M B ~ 1.5GB
SDRAM(256M b techn ology). T he DR AM inst allation position refer to Figure 3.1,
and notice the Pin 1 of DIMM module must match with the Pi n 1 of DIMM socket.
Insert the DRA M DIM M module into the DIM M socket at Ver tical angle. If ther e
is a wrong direc tion of Pin 1, t he DRAM DIMM module could not be inser ted into
socket completely.

3.5. CPU SPEED SETUP

The system bus fr equency can be switched at 66MHz, 100MHz and 133 MHz by
adjusting DIP SW2. The CPU fre quency rat io can be swi tched fr om X 3 to X 9 .5
by adjusting DIP SW1. The user can set up CPU speed for 300~733MHz
processors by adjusting SW1 and SW2 properly.

The CPU speed must match with the frequency RATIO. It will cause system
hanging up if the frequency RATIO is higher than CPU's.

The CPU is a sensitive electric component and it can be easily

damaged by st atic electricity, so users must keep it away from metal
surface when the CPU is installed onto main board.

3.6. CMOS RTC & ISA CFG CMOS SRAM

The mainboard contains RTC & CMOS SRAM on board. They have a power
supply from exter nal battery to keep the DAT A inviolate & ef fective. T he RTC is
a REAL-TIM E CLOCK device, w hich provides the DAT E & TIM E to system. The
CMOS SRAM is used for keeping the information of system configuration, so
the system can automatically boot OS ev ery time. Since the lifet ime of internal
battery is 5 years, the user can change a new Battery to replace old one when
it has consumed.

3.7. SPEAKER CONNECTOR INSTALLATION

There is a speaker in AT syst em for sound purpose. The 4 - Pins connector

SPK

is used to connect speaker. Anode connects +, Cathode connects −.

3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION

The RESET sw itch on pa nel provides u sers with H ARDWARE RESET fu nction.
The system will do a cold start aft er the RESET button is pressed and released
by user. The RESET switch is a 2 PIN connector and should be installed to
on main board.

3.9. POWER LED CONNECTOR INSTALLATION

System has power LED lamp on the panel of case. The power LED will light
on/off or flash to indicate which step on the system. The connector should be
connected to PWR of main board in correct direction.

3.10. IDE & ATAPI DEVICE INSTALLATION

There are tw o-En hanced P CI IDE port s (
ATAPI standard SPE C. Any one ID E port can connected to tw o ATA PI devices
(IDE Hard Disk, CD-R OM & T ape Drive r), so tota l four AT API device s can exist

3.11. PERIPHERAL DEVICE INSTALLATION

After the I/O device installation and jumpers setup, the main board can be
mounted into the case and fixed by screw. To complete the main board
installation, the peripheral device could be installed now. The basic system
needs a display interface card. If the PCI - Bus device is to be installed in the
system, any one of four PC I - Bus slots can be used.

3.12. KEYBOARD & PS/2 MOUSE INSTALLATION

The main board supports PS/2 Mouse. The BIOS will auto detect whether the
PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is
installed. After installing the peripheral device, the user should check
everything again, and prepare to power-on the system.

The value of the base memory is typically 512 K for syst ems w ith
512 K memory install ed on the motherbo ard, or 640 K for systems
with 640 K or more memory installed on the motherboard.

Extended Memor y

The BIOS determines how much extended memory is present

Expanded Memory

Expanded Memory in memory defined by the Lot us/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

This refers to the memory located in the 640 K to 1024 K address
space. This is memor y that can be used for di fferent application s.

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.
