FEATURES

3WXM4 Features:

•3WXM4 is based on the Intel CeleronTMProcessor operating at 300A

~ 466MHz (66MHz) or 100MHz FSB for feature processor on PPGA 370

socket. The board is configured by an Easy-Setting-Single-Jumper (E.S.S.J.)

to match your CPU clock speed.

• CPU clock ratio from 3x~8x setting in BIOS.

• Designed with Intel’s 810 chipset.

• Supports up to 512 MB of DRAM (minimum of 16 MB) on board, You

can use 168-pin DIMM x 2. It will run Synchronous DRAM memory

(SDRAM) at 100MHz.

• 64-bit system memory interface with optimized support for SDRAM at

100MHz.

• Integrated 2D & 3D Graphics Engine, H/W Motion Compensation Engine,

230MHz DAC and 4MB Display Cache

• AC’97 2.1 Audio CODEC onboard.

• Supports (3) 32 bit PCI slots, provides (2) independent high performance

PCI IDE interfaces capable of supporting PIO Mode 3/4 and Ultra DMA

66 devices. The 3WXM4 supports (3) PCI Bus Master slots and a

jumperless PCI INT# control scheme which reduces configuration confu-

sion when plugging in PCI card(s).

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

IDE interfaces.

• Designed with Winbond W83627HF LPC (Low Pin Count) I/O: (1) floppy

port, (1) parallel port (EPP, ECP), and (2) serial ports (16550 Fast UART)

Features3WXM4

• Includes a PS/2 mouse connector.

• Allows use of a PS/2 keyboard.

• Features Award Plug & Play BIOS. With 4MB(FWH) Flash Memory you

can always upgrade to the current BIOS.

•3WXM4 utilizes a Lithium battery which provides environmental

protection and longer battery life.

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

(82801) chip provides the means for connecting PC peripherals such as;

keyboards, joysticks, speaker, and mouse.

• 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, allow

system to be turned on remotely.

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

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

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

(KBPO).

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

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

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

• Supports the AMR Connector for enables the software modem.

The Modem Riser Card (MR) or Modem Codec (MC) must be secondary

only on the 3WXM4.

Easy Installation Procedure

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

Configure Jumpers to match your hardware

Configure Jumpers

The 3WXM4 designs all motherboards with the fewest jumpers to make

your installation fast and easy.

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

moving on to step 2.

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

physical orientation.

System Memory Configuration

Memory Layout

The 3WXM4 supports (2) 168-pin DIMMs (Dual In-line Memory

Module). The DIMMs can be either EDO (Extended Data Out) or SDRAM

(Synchronized DRAM).

• 100MHz system memory bus frequency. Even if the system host bus is

66MHz.

• 8MB to 256MB using 16MB/64MB technology (512MB using 128MB

technology).

• 256MB Support Registered synchronous DRAM Memory Modules.

• We recommend to installed the “PC/100MHz SDRAM Spec.”, using

DIMM SDRAM must be 125MHz (-8ns) bus speed. If used 100MHz

(-10ns) SDRAM may be critical timing for the motherboard.

• DIMM SDRAM may be 100MHz (-10ns) or 125MHz (-8ns) bus speed.

Figure 2 and Table 1 show several possible memory configurations using

* SDRAM only supports 16, 32, 64, 128, 256MB DIMM modules.

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, there is a special feature to make the system to

go into suspend mode when the button is pressed momentarily.)
