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 100~300 mA 5V Stand-By current(rest
with keyboard require), you can power on your system by
entering password from the Keyboard after setting the
“Keyboard power on” jumper (JP1) and password in CMOS
Setup.

3. Modem Ring-On on COM B.

4. Wake-up on LAN supports(on JP8): Your ATX power supply
must support larger than 720 mA 5V Stand-By current.

5. Support 3 steps ACPI LED.

6. Support LDCM

I. Quick Installation Guide :

CPU SPEED SETUP

The system bus speed can be selectable between 66.6MHz and 100MHz. The
user can select the system bus speed (JP6) and change the DIP SWITCH (SW)
selection to set up the CPU speed for 200 - 633MHz processor.

M

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

system hanging up if the frequency RATIO is higher than CPU's.

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 mainboard package should contain the following:

• The 6BXDS mainboard.

• The Retention Mechanism & Attach Mount

• USER'S MANUALS for mainboard & . SCSI device.

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

• Diskettes and CD for Mainboard Utility.

• External SCSI port adapter.

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.

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

3.4. DRAM INSTALLATION

The mainboard can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM. The DRAM memory system on mainboard consists of
bank 0, 1, 2 & bank 3.

Since 168 pins DIMM module is 64 bits width, using 1 PCS which can match a
64 bits system. The total memory size is 8 MB ~ 1 GB 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 couldn't be inserted into socket completely.

3.5. CPU SPEED SETUP

The system bus speed can be set to 66.6MHz or 100MHz form the jumper
(JP6). The user can change the DIP SWITCH (SW) 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.

Set system speed to 66MHz: JP6 pin 1-2 short will cause system
always run at 66 MHz FSB (Front Side Bus).

JP6

Set system speed to 100MHz: JP6 all pins open will cause system
always run at 100MHz FSB.

JP6

Set system speed to Auto: JP6 pin 2-3 short will detect system speed
66/100MHz FSB automatically.

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
SPK 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 button is pressed 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. SCSI DEVICE INSTALLATION

There are two SCSI channels on board.
There are two SCSI ports on Channel A. One is 8 bits SCSI port for SCSI-2 or
ULTRA SCSI device, the other is 16bit SCSI port for wide or ULTRA Wide
SCSI device.
Channel B is 16 bits SCSI port for wide or ULTRA Wide SCSI device.
Total 30 SCSI devices (include 8bit SCSI devices) can exist in a system.
The low byte terminator (used for 8bit SCSI port) and high byte terminator
(used for Wide SCSI port) turning "ON" or "OFF" are controlled by BIOS
SETUP (in the INTEGRATED PERIPHERALS SETUP PAGE).

3.12. PERIPHERAL DEVICE INSTALLATION

After the I/O 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. If the PCI - Bus device is to be installed in the
system, any one of four PCI - Bus slots can be used.

3.13. KEYBOARD & PS/2 MOUSE INSTALLATION

The main board supports PS/2 Mouse (J1). 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.

• 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

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.
