USER'S MANUAL

1. System power on by PS/2 Mouse: First, enable this function
in CMOS Setup, then you 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 (depends
on the specification of keyboards), you can power on your
system by entering password from the keyboard after
setting the “Keyboard power on” password in CMOS Setup.

3. Supports 3 steps ACPI LED.

4. Modem Ring-On. (COM A , B).

5. Wake-Up on LAN. (The ATX power supply supports larger
than 720 mA 5V Stand-By current)

I. Quick Installation Guide :
CPU SPEED SETUP

The system bus speed is selectable between 66 / 100 MHz. The user can
select the system bus speed (SW1) and change the DIP SWITCH (SW2)
selection to set up the CPU speed for 233 - 650MHz processor.

Set System Bus Speed

The CPU speed MUST match with the frequency RATIO. It will cause
system hanging up if the frequency RATIO is higher than that of CPU.

Note: We don’ t recommend you to set up your system speed to 75, 83,

112, 133 MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals.
Whether your system can run under 75, 83, 112, 133 MHz
properly will depend on your hardware configurations: CPU,
SDRAM, Cards, etc.

Introduction

1.6 What is AGP

?

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

The AGP port can be used either as fast PCI port (32-bits at 66MHz vs.32-Bits
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 transmit
data at 533MB/sec (66.6*2*4). The read-queue can be used to pipeline reads
– removing the effects of the reads-latency. Side band addressing can be
used to transmit the data address on a separate line in order to speed up the
transaction.

3. HARDWARE INSTALLATION

3.1. UNPACKING

The main board package should contain the following:

• The 6VXE main board.

• The Retention Mechanism & Attach Mount

• USER’ S MANUAL for main board.

• Cable set for IDE, Floppy devices.

• Diskette or CD for main board Utility.(Bus Master + AGP Driver + 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 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 main board 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.

Hardware Installation

3.4. DRAM INSTALLATION

The main board can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must be 67~100 MHz for SDRAM
when system bus speed is set to 66MHz. 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.

Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM
module may match a 64 bits system. The total memory size is 8 MB ~ 768MB
SDRAM. The DRAM installation position refer to Figure 3.1, and notice the Pin
1 of DIMM module must match with the Pin 1 of DIMM socket. Insert the
DRAM DIMM module into the DIMM socket at Vertical angle. If there is a
wrong direction of Pin 1, the DRAM DIMM module could not be inserted into
socket completely.

3.5. CPU SPEED SETUP

The system bus speed can be set to 66 / 100 MHz form the DIP SWITCH
(SW1). The user can change the DIP SWITCH (SW2) selection to set up the
CPU speed for different processors. The CPU speed must match with the
frequency RATIO and Front Side Bus (FSB) speed. It will cause system
hanging up if the frequency RATIO and FSB Speed do not match with the
CPU.

damaged by static 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

There're RTC & CMOS SRAM on board; they have a power supply from
external 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 system configuration, so the
system can automatically boot OS every time. Since the lifetime of internal
battery is 5 years, the user can change a new Battery to replace old one after
it cannot work.

3.7. SPEAKER CONNECTOR INSTALLATION

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

SPKR is used to connect speaker.

3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION

The RESET switch on panel provides users with HARDWARE RESET
function. 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 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 two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which following
ATAPI standard SPEC. Any one IDE port can connected to two ATAPI devices
(IDE Hard Disk, CD-ROM & Tape Driver), so total four ATAPI devices can exist
in a system. The HD is the active LED port for ATAPI devices.

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 PCI - 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.
