FEATURES

BX3 Features:

•BX3 is based on the Pentium®II or Pentium®III Processor operating at 233

~ 333MHz (66MHz) or 350 ~ 500MHz (100MHz) on Slot 1. The board is

configured by an Easy-Setting-Dual-Jumper (E.S.D.J.) to match your CPU

clock speed.

•Designed with Intel’s 82443 BX AGPset.

•Supports up to 768 MB of DRAM (minimum of 16 MB) on board, You can

use 168-pin DIMM x 3. It will automatically detect Extended Data Output

(EDO) DRAM at 66MHz only or Synchronous DRAM memory (SDRAM) at

66MHz or 100MHz (please see Section 3-2).

•BX3 will support Error Checking and Correcting (ECC) when using paritys

DRAM memory modules. This will detect multiple bit errors and correct 1-bit

memory errors.

•Supports (2) 16 bit ISA slots, (5) 32 bit PCI slots, (1) AGP slot and provides

(2) independent high performance PCI IDE interfaces capable of supporting

PIO Mode 3/4 and Ultra DMA 33 devices. The BX3 supports (5) PCI

Bus Master slots and a jumperless PCI INT# control scheme which reduces

configuration confusion when plugging in PCI card(s).

•Supports ATAPI (e.g. CD-ROM) devices on both Primary and Secondary IDE

interfaces.

•Designed with Winbond W83977TF Multi I/O: (1) floppy port, (1) parallel port

(EPP, ECP), and (2) serial ports (16550 Fast UART).

Note: Japanese “Floppy 3 mode” is also supported

•Includes a PS/2 mouse connector.

•Allows use of a PS/2 keyboard.

•Features Award Plug & Play BIOS. With Flash Memory you can always

upgrade to the current BIOS as they are released. (http://www.2themax.com

•BX3 utilizes a Lithium battery which provides environmental protection and

longer battery life.

•Supports the Universal Serial Bus (USB) connector. The onboard PIIX4E chip

provides the means for connecting PC peripherals such as; keyboards,

joysticks, telephones, and modems.

•Built-in ATX 20-pin power supply connector.

•Software power-down when using Windows®95/98.

•Supports ring-in feature (remote power-on through external modem, allows

system to be turned on remotely).

•Resume by Alarm - Allows your system to turn on at a preselected time.

•Power Loss Recovery - In the event of a power outage your system will

automatically turn itself back on without user intervention.

•Supports CPU Hardware sleep and SMM (System Management Mode).

•Supports Desktop Management Interface (DMI) facilitating the management

of desktop computers, hardware and software components and peripherals,

whether they are stand-alone systems or linked into networks. (optional)

•Supports Hot key, Any key or password Keyboard power ON function

(KBPO).

•Supports USDM software to offer motherboard various status on Windows®

95/98, or Windows®NT 4.0/5.0.

•Supports the CPU, PWR and Chassis fan Auto stop in sleep mode.

•Supports the System Power LED (PANEL) blinks in the sleep mode.

•Built-in WOL (Wake On LAN) Connector.

• Built-in SB-LINK Header for Creative Blaster®AWE64D PCI Bus Sound

Card.

Easy Installation Procedure

The following must be completed before powering on your new system:

Configure Jumpers to match your hardware

Install memory chips

Device Connectors

Configure Jumpers

We design this motherboard with the an ESDJ to make your install fast and easy.

The following will describe all of the ESDJ that you are required to set before moving

on to step 2.

Note: The ESDJ as depicted as shown (Figure 1) in their correct physical

orientation.

Note: Based on the implementation of Intel 440BX PCIset, BX3 is able to

provide two host bus frequencies -- either 66 or 100MHz for Slot1 processor and

memory operating. The default is set at 100MHz once Pentium®II processor to

be mounted onto this motherboard. However, no matter what kind of Slot1 proces-

soryouinstalled,itshouldcomewithrightmemorymodulesfornormalandstable

operation. For example, if you install a Pentium®III processor, you should use

the SDRAM module with 100MHz based(or above) to match the CPU speed.

Furthermore,one thingyou mayneed tobear inmind, beforethe CPUinstallation, it

is anyway our advice to use JP3 and set up right speed of Slot1 processor at any

time.

System Memory Configuration

Memory Layout

The BX3 supports (3) 168-pin DIMMs (Dual In-line Memory Module). The

DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized

DRAM). The DIMMs may be installed using just one chip.

•We recommend using SDRAM DIMM can not mixing

with EDO DIMM modules.

• The EDO DIMM only support pentium®II Processor at 66MHz, not

support Pentium III Processor at 100MHz.

• We recommend when installed the 100MHz Pentium III Processor

using DIMM SDRAM must be 125MHz (-8ns) bus speed. If used

100MHz (-10ns) SDRAM may be critical timing for the

motherboard.

• About the “PC/100 SDRAM spec.” information you may visit Intel’s

home page at:

http//developer.intel.com/design/pcisets/memory/index.htm

• DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or

125MHz (-8ns) bus speed.

Power On/Off - This is connected to the power button on the case.

Using the Soft-Off by Pwr-BTTN feature, you can choose either

Instant Off (turns system off immediately), or 4 sec delay (you need to

hold the button down for 4 seconds before the system turns off). When

the system is in 4 sec delay mode, we has added a special feature to

make the system go into suspend mode when the button is pressed

momentarily.
