USER'S MANUAL

1. System power on by PS/2 Mouse: If you are using ATX power
supply, you are able to 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 720 mA 5V Stand-By current, 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. (The ATX power supply supports larger
than 600 mA)

5. Support 3 steps ACPI LED selectable.

CPU SPEED SETUP

The system bus speed can be selectable between 66.6MHz and 100MHz. The
user can select the system bus speed (JP10) 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. 32­bits 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 further speed the transaction.

3. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

• The 6BXD mainboard.

• The Retention Mechanism & Attach Mount

• USER'S MANUAL for mainboard.

• Cable set for IDE¡BFloppy device.

• Diskette or CD for Mainboard Utility Controller.

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 ATX system board. It is assumed that the
chassis is designed for a standard ATX mainboard mounting.

Place the chassis on the anti-static mat and remove the cover. Take the clips,
stand-off and screws for mounting the system board, and keep them

3.4. DRAM INSTALLATION

The mainboard can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must be 50 or 60 ns for EDO &
67~100 MHz for SDRAM. The DRAM memory system on mainboard
consists of bank 0, 1, 2 & bank 3.

Because the 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 EDO or
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.

3.6. 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. Due to the life-time of
Battery internal battery is 5 years, the user can change a new Battery to
replace old one after it can not work.

M Danger of explosion if battery is incorrectly replaced.
M Replace only with the same or equivalent type recommended by the

manufacturer.

M Dispose of used batteries according to the manufacturer’ s instructions.

3.7. SPEAKER CONNECTOR INSTALLATION

There is always a speaker in AT system for sound purpose. The 4 - Pins
connector J11 is used to connect speaker.

The speaker can work well in both direction of connector when it is installed
to the connector J11 on mainboard.

3.8. 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 J10 on mainboard.

3.9. POWER LED CONNECTOR INSTALLATION

There are system power LED lamps on the panel of case. The power LED
will light on when system is powered-on, which is connected to a 3 PIN
connector.

The connector should be connected to JP7 of mainboard in correct direction.

3.10. IDE & ATAPI DEVICE INSTALLATION

There are two Enhance PCI IDE ports 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 J7 is the active LED port for ATAPI device.

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 five PCI ­Bus slots can be used.

3.13. KEYBOARD & PS/2 MOUSE INSTALLATION

The main board supports PS/2 connector type keyboard & Mouse (J3).
The BIOS will auto detect whether the PS/2 Mouse is installed or nor &

assign IRQ12 for Mouse port if which was installed.
After installing the peripheral device, the user should check everything again,

and prepare to power-on the system.

3.14. KEYBOARD SETTING FUNCTION

After booting the O.S., there are some special functions used by keyboard as
follows:

"CTRL_ALT_DEL" − Pressing these keys simultaneously will cause

system to Warm Start (Software Reset).

• 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.

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.
