Installation Notice

The manufacturer recommends using a grounded plug to ensure proper
motherboard operation. Care should be used in proper conjunction with a
grounded power receptacle to avoid possible electrical shock. All integrated
circuits on this motherboard are sensitive to static electr icity. To avoid damaging
components from electrost atic discharge, please do not remove the board from the
anti-static pa cking before disc harging any static electricity to your body, by wearing
a wrist-grounding strap. The manufacturer is not responsible for any damage to the
motherboard due to improper operation.

Chapter 1. Introduction

ENDAT-4946i/M supp orts high performance proce ssor of Intel® Celeron® M 423
(for ENDAT-4946M), Intel® Core™ Solo, Intel® Core™ Duo and Intel® Core™2
Duo processor (for ENDAT-4946i) with 533 and 667 Front Side Bus. It also
supports high speed DDR-2 memory with 64-bit wide interfaces with non-ECC
DIMM (up to 2GB). Only Double-Data- Rate Two Synchronous Dynamic Random
Access Memory is supported and the speed of memory can be 533 and 667 MHz.

ENDAT-4946i/M provides an integrated graphics (Intel® Graphics Media
Accelerator 950) accelerator delivering cost competitive 3D, 2D, and video
capabilities.
ENDAT-4946i/M video engines support video conferencing and other video
applications. Instead of a dedicated local graphics memory interface,
ENDAT-4946i/M uses a UMA configuration for optimal memory utilization and
performance that deliver 3D graphics with sharp images, fast rendering, smooth
motion and extreme detail.

ENDAT-4946i/M contains one integrated Serial ATA host controllers capable of
independent DMA operation on two ports. The SATA controllers are completely
software transparent with the IDE interface, while providing a lower pin count and
higher performance. The data transfer rate is up to 300 MB/s.

ENDAT-4946i/M is an ideal model for various kind of application:

- POS system

- KIOSK

- Interactive system

- Airport Terminal Controller

- Industrial controller

- Digital entertainment

- Embedded system equipment

1-2Unpacking

The motherboard comes securely packaged in a sturdy cardboard shipping carton.
In addition to the User’s Manual, the motherboard package includes the followi ng
items:

ENDAT-4946i/M System Board
HDD / IO Cables
LCD cable (Optional)
CDROM Driver includes: D rivers for Windows 2000, XP and AM I / A W ARD FLASH

ROM utilities.
Driver utilities for on-board VGA drivers, LAN adapter
If any of these items are missing or damage, please contact the dealer from whom

you purchase the motherboard. Save the shipping material and carton in the event
that you want to ship or store the board in the future.

Note:

Please leave the motherboard in its original package until you are ready to
install it!

1-3. Electrostatic Discharge Precautions

Make sure you properly ground yourself before handling the motherboard, or other
system components. Electrostatic discharge can easily damage the components.
Note: You must take special precaution when handling the motherboard in dry or
air-conditioned environments.

2-2. Installing Memory

ENDAT-4946i/M system board offers one 240pin DDR-2 SDRAM socket supports
up to 2GB memory and the speed can be 533 / 667 MHz.

2-3. Shared VGA Memory

ENDAT-4946i/M is usin g built-in I NTEL® GMA950 Graphic with INTEL DVMT 3.0
up to 224MB of system memory. The amount of video memory on motherboard
determines the number of colors and the video graphic resolution.

2-4. Assigning IRQs for Expansion Cards

Some expansion cards require an IRQ (Interrupt request vector) to operate.
Generally, each IRQ must be exclusively assigned to specific use. In a standard
design, there are 16 IRQ available with 11 of them alr eady in us ed by other p a rt of
the system.

Some PCI expansion cards need IRQ; any remaining IRQ could be assigned to
PCI Bus. Microsoft’s Diagnostic (MSD.EXE) utility included in the Windows
directory can be used to see their map. Clients can not have more than one device
apply the same IRQ in the system or it will cause the system hang up, crash, and
unexpected results. To simplify the pr ocess, this motherboard com plies with the
Plug and Play (PnP) specifications, which was developed to allow automatic
system configuration. Whenever a PnP-compliant card is added to the system,
PnP card and IRQs will automatically assigned if available. The PCI and PnP
configuration in the B IOS setup utility can indicate w hich IRQs have being used by
Legacy cards.

In the PCI Bus design, the BIOS is automatically assigned an IRQ to a PCI slot that
has a card in it which requires an IRQ. To install PCI cards via riser card, you need
to set the correct “ADSEL” and “INT” (interrupt) assignment on t he jumper of riser
card.

2-5. Watchdog Timer

Watchdog Timer (WDT) is a special design for system monitoring to secure the
system work normally. WDT has an independent clock from the oscillator and
could set time and clear/refresh WDT counter function. When time is up, WDT wil l
send hardware RESET signal to reset system.

ENDAT-4946i/M provides an integrated graphics (Intel® Graphics Media
Accelerator 950) accelerator delivering cost competitive 3D, 2D, and video
capabilities. It contains an extensive set of instructions for 3D operations, BLT
(Block Level Transfers) and Stretch BLT operations, motion compensation,
overlay, and display control. ENDAT-4946i/M video engines support video
conferencing and other video applications. Instead of a dedicated local graphics
memory interface, ENDAT-4946i/M applies UMA configuration for optimal memory
utilization and performance that deliver 3D graphics with sharp images, fast
rendering, smooth motion and extreme detail.

The Intel® 945GM Express chipset's low power design enables up to 28% less
average power consumption compared to previous generations. Featuring the
Intel® Graphics Med ia Accelerato r 950, th e Intel 9 45GM Expr ess chipse t deliver s
up to 2 x improvements in graphics performance over the previous generation
chipset. The Intel® 945GM Express chipset enables up to 25% higher data
transfer rate compared to the previous generation bus speed.

ENDAT-4946i/M applies Intel® DVMT 3.0 for optimum the system utilization via
system chipset. DVMT is a concept be applied in the Intel® 945GM chipset
wherein the optimum amount of memory is dynamically allocated and de-allocate d
as needed for balanced graphics and system performance, through Intel® Direct
AGP and a highly efficient memory utilization scheme.

The on-board INTEL® GMA950 Graphic Controller supports a full AGP
implementation internally to remain compatible with existing software and
programming models. Howe ver, since the en gine is integrated, it enjoys a higher
bandwidth and lower lat ency than is possible with discrete solutions.

The controller of ENDAT-4946i/M supports 3 types of display: CRT, DVI and LVDS
panel.

34

The ENDAT-4946i/M System Board

4-2. LVDS Panel Feature (optional)

The on-board graphic controller supports industry standard LCD panel, LVDS
interface only, with 1 channel (18 or 24) and 2 channels (36 or 48bit) data width.

LVDS interface provides low v oltage, high speed and low EMI serial DC-balanced
differential data via optional onboard LVDS.

The flat panel interface provides or supports fo llowin g functio ns for various panels:

- Generates LVDS flat panel channels like clock and data channel.

- Generates different video data formats to directly drive different types of
panels (18, 24, 36 or 48bit)

- Wide screen resolution as 16:9 or 16:10.

- Vertical and horizo ntal expansion of vide o displays to LCD panel resolution

- Vertical and horizontal centering

- Panel power sequence

Please note that the default setting is with “CRT”. If the LCD display features is
