I. Quick Installation Guide :

CPU SPEED SETUP

The system bus speed is selectable between 66.6MHz and 100 MHz. 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.

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.

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

II. Set system speed to 100MHz: JP6 pin 1-2-3 open will cause

system always run at 100MHz FSB.

III. Set system speed to Auto: auto detect system speed

(66/100MHz FSB)



There are two ways to set system speed

1. 66MHz (JP6) (1-2 short) or Auto detect (2-3 short)

2. 100MHz (JP6) (1-2-3 open) or Auto detect (2-3 short)

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.

Hardware Installation

3. HARDWARE INSTALLATION

3.1. UNPACKING

The main board package should contain the following:

• The 6BX 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.

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, ex tract 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 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, 2 & bank 3.

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 ~ 1 GB
SDRAM. The DR AM installation position refer to Figure 3.1, and notice the Pin
1 of DIMM module must match with the Pin 1 of D IMM 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 66.6MHz 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.

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
REAL-TIME 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.

manufacturer.

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 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 follow ing
ATAPI standard SPEC. Any one IDE port can connected to two ATAPI devices
(IDE Hard Disk, CD-R OM & T ape Driv er), so total four ATAPI dev ices can ex ist
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 (J2). 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.

stop for all other errors

All, But Disk/Key The system boot will not stop for a keyboard or disk

error; it will stop for all other errors

• Memory

4-6

BIOS Configuration

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 sy stems 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.
