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-4946i/M supports high performance processor 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
