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

FeaturesBX3
•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
Card.

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.

CPU Selection
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 processor you installed, it should come with right memory modules for normal and stable
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 thing you may need to bear in mind, before the CPU installation, 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
support Pentium III Processor at 100MHz.
• W e 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.

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.
