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 donot 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-9401F/H supports high performance processor of Intel® Celeron® M 423,
Intel® Core™ Solo, Intel® Core™ Duo andIntel® Core™2 Duo processor 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-9401F/H provides an integrated graphics (Intel® Graphics Media
Accelerator 950) accelerator delivering cost competitive 3D, 2D, and video
capabilities.
ENDAT-9401F/H video engines support video conferencing and other video
applications. Instead of a dedicated local graphics memory interface,
ENDAT-9401F/H 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-9401F/H 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-9401F/H is an ideal model for various kind of application:
-POS system
-KIOSK
-Interactive system
-Airport Terminal Controller
-Industrial controller
-Digital entertainment
-Embedded system equipment

2-3. Installing Memory
ENDAT-9401F/H system board offers one 240pin DDR-2 SDRAM socket supports
up to 2GB memory and the speed can be 533 / 667 MHz.
2-4. Shared VGA Memory
ENDAT-9401F/H is using built-in INTEL® 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.
2-5. 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
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.
