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 electricity. To avoid damaging
components from electrostatic discharge, please do not remove the board from the
anti-static packing before discharging 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-4066i supports high performance processor of Intel® Pentium4®,
Celeron® and Celeron D ® with 400 and 533 Front Side Bus. It also supports high
speed DDR memory with 64-bit wide interfaces with non-ECC DIMM (up to 1GB).
Only Double Data Rate (DDR) SDRAM memory is supported and the speed of
memory can be 266, 333 and 400 MHz.
ENDAT-4066i provides an integrated graphics (Intel® Extreme Graphics 2)
accelerator delivering cost competitive 3D, 2D, and video capabilities.
ENDAT-4066i video engines support video conferencing and other video
applications. Instead of a dedicated local graphics memory interface, ENDAT-4066i
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-4066i 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 150 MB/s.
ENDAT-4066i is an ideal model for various kind of application:
-POS system
-KIOSK
-Interactive system
-Airport Terminal Controller
-Industrial controller
-Digital entertainment
-Embedded system equipment

The motherboard comes securely packaged in a sturdy cardboard shipping carton.
In addition to the User's Manual, the motherboard package includes the following
items:
ENDAT-4066i System Board
HDD / IO Cables
LCD cable (Optional)
CDROM Driver includes: Drivers for Windows 98, ME, 2000, XP and AMI / AWARD
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!

ENDAT-4066i system board offers one 184pin DDR SDRAM socket supports up to
1GB memory and the speed can be 200/ 266/ 333/ 400.
2-3. Shared VGA Memory
ENDAT-4066i isusing built-in AGP VGAcontroller with INTELDVMT up to 96MB of
system memory. The amount of video memory on motherboard determines the
number of colors and the video graphic resolution.

The default INT/AD-select for ENDAT-4066iAll-In-One motherboard is listed in the
above table.
2-5.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 already in used by other part 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 orit willcause the system hang up, crash, and unexpected
results. To simplify the process, this motherboard complies 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 BIOS
setup utility can indicate which IRQs have being used by Legacy cards.
In the PCI Bus design, the BIOS is automatically assigned an IRQ to a PCI slot that

User’s Manual 15
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 the jumper of riser
card.

Watchdog Timer (WDT) is a special design for system monitoring to secure the

set time and clear/refresh WDT counter function. When time is up, WDT will send
hardware RESET signal to reset system.

Chapter 4. VGA, LCD Feature
4-1. VGA Feature
ENDAT-4066i provides an integrated graphics (Intel® Extreme Graphics 2)
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-4066i video engines support video conferencing and other video
applications. Instead of a dedicated local graphics memory interface,
ENDAT-4066i applies UMA configuration for optimal memory utilization and
performance that deliver 3D graphics with sharp images, fast rendering, smooth
motion and extreme detail.
High bandwidth access to data is provided through the system memory port.
ENDAT-4066i can access local graphics data located in system memory at 2.1
GB/s (DDR266) 2.7 GB/s (DDR333), or 3.2 GB/s (DDR400) in single-channel
mode.
ENDAT-4066i applies Intel® DVMT for optimum the system utilization via system
chipset. DVMT is a concept be applied in the Intel® 865GV chipset wherein the
optimum amount of memory is dynamically allocated and de-allocated as needed
for balanced graphics and system performance, through Intel® Direct AGP and a
highly efficient memory utilization scheme.
The on-board Graphics Controller supports a full AGP implementation internally to
remain compatible with existing software and programming models. However,
since the engine is integrated, it enjoys a higher bandwidth and lower latency than
is possible with discrete solutions.
The controller of ENDAT-4066i supports 2 types of display: CRT and LVDS panel .
32 The ENDAT-4066i System Board
4-2. LVDS Panel And TV Feature (optional)
These 2 devices are alternate feature; can not exist on the same system at the same time.
LVDS Panel Interface
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 voltage, high speed and low EMI serial DC-balanced
differential data via optional onboard LVDS.
The flat panel interface provides or supports following functions 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 horizontal expansion of video displays to LCD panel resolution
- Vertical and horizontal centering
- Panel power sequence
Please note that the default setting is with “CRT only”. If the LCDdisplay features is
required, the setting will need to be revised in the system BIOS setting: “Display Device”
under “Advanced Chipset Features
” unless clients specified the display type while order.
