1. Introduction
Thank you for choosing POS-478 Socket 478 Pentium 4 with Multimedia POS
Control Board. POS-478 board is an POS form factor board equipped with high
performance processor and advanced high performance multi-mode I/O, designed
for the system manufacturers, integrators, or VARs that want to provide all the
performance, reliability, and quality at a reasonable price.
POS-478 is built-in with AGP4X VGA (Intel 845GV), which is a VGA controller
supporting 3D graphics capability to provide up to 2048x1536x16-color resolution.
The onboard VGA shares 8MB system DDR-SDRAM. POS-478 provides a highly
integrated scaling IC with LVDS Transmitter with a scaled resolution up to SXGA for
single pixel Input. It supports up to 48-bit color TFT LCD.
An advanced high performance super AT I/O chip — ITE IT8712 is used in POS-478
board. Both on-chip UARTs are compatible with the NS16C550. The parallel port
and IDE interface are compatible with IBM PC/AT architecture.
POS-478 has one 10/100 Fast Ethernet LAN built-in (ICH4) and one Intel 82540
Gigabit LAN. They are of high performance networking functions and low power
features.
POS-478 is equipped with IEEE1394 controller (TI TSB43AA22). You can connect
it to your 1394 devices. POS-478 also provides two Serial ATA ports to connect
with Serial ATA devices.
POS-478 uses the advanced Intel 845GV Chipsets which are 100% software
compatible chipset with PCI 2.2 standard.

2.2 Unpacking Precautions
Some components on POS-478 with Multimedia POS Control Board are very
sensitive to static electric charges and can be damaged by a sudden rush of
power. To protect it from unintended damage, be sure to follow these
precautions:
•Ground yourself to remove any static charge before touching POS-478.
You can do it by using a wrist strap connected to the ground or by
frequently touching any conducting materials connected to the ground.
•Handle your POS-478 by its edges. Do not touch IC chips, leads or
circuitry.
•Do not plug any connector or jumper when the power is on.
