1. Introduction
1.1 Description
The 2808000 all-in-one Mini ITX is designed to fit a high performance Pentium 4 LGA 775
based processor and compatible for high-end computer system application with PCI bus
architecture. It is made to meet today’s demanding pace, and keep complete compatibility
with hardware and software designed for the IBM PC/AT. The on-board devices support
one PCI slot and integrated graphics and on-board Dual Marvell Gigabit Ethernet controller.
It’s beneficial to build up a high performance and high data availability system for VARs, or
system integrators.
2808000 SERIES support the following processors:
zIntel ® Pentium®4 processor Socket LGA 775 supporting Hyper-Threading
technology based on 0.90 and 0.65 micron (CPUID = 0xh).(only support 5 series
and 6 series)
zIntel ® Celeron D®processor Socket LGA 775 supporting Hyper-Threading
technology based on 0.90 and 0.65 micron (CPUID = 0xh). (only support 5 series
and 6 series)
This Mini ITX can run with Intel Socket LGA 775 Pentium 4(HT) processors, and support
DIMM up to 2GB dual-channel DDR Memory. The enhanced on-board one PCI-IDE
interface can support 2 drives up to PIO mode 4 timing and Ultra ATA33/66/100
synchronous mode feature, and 4 Serial ATA connectors high-speed data transfers at up to
150 MB/s. The on-board Super I/O chipset support two serial ports, one SIR (Serial Infrared)
port, and one parallel port. Two high performance 16C550-compatible UARTs provide
16-byte send/receive FIFOs and the multi-mode parallel port supports SPP/EPP/ECP
function, two RS-232 serial port interface. Besides, H/W monitor function, and supports 4
Serial ATA interface , Intel High Definition Audio as 5.1 surround sound , Hi-Speed USB 2.0
x 8 ports offer up to 40X greater bandwidth over USB 1.1 Also provide dual display function
by VGA and DVI interface..
The Mini-ITX standard makes the 2808000 SERIES work with the one slot PCI. One 6-pin
Mini-DIN connectors are provided to connect PS/2 mouse and keyboard. The on-board
Flash ROM is used to make the BIOS update easier. The high precision Real Time Clock
/calendar is built to support Y2K for accurate scheduling and storing configuration
information. One 24-pin standard connector is designed to supportATX power function. A
feature of CPU overheat protection will give user more security and stability. All of these
features make 2808000 SERIES excellent in stand-alone applications.
Note :(1) The 2808000 series only support Intel Pentium 4 processor 5 series and 6 series
for 0.90 and 0.65 micron.
(2) The 2808000 series only support DDR 400 memory module.

2. Hardware Configuration Setting
This chapter gives the definitions and shows the positions of jumpers, headers and
connectors. All of the configuration jumpers on 2808000 are in the proper position. The
default settings shipped from factory are marked with an asterisk ().
In general, jumpers on the Mini-ITX are used to select options for certain features. Some of
the jumpers are designed to be user-configurable, allowing for system enhancement. The
others are for testing purpose only and should not be altered. To select any option, cover
the jumper cap over (SHORT) or remove (NC) it from the jumper pins according to the
following instructions. Here, NC stands for “Not Connect”.

GPIO(1)/TLDET* pin pulling low.
TMDSDATA I/O DVI I2C Data: This signal is used as the I2C DOC clock for a digital display
connector (i.e. TV-Out Encoder , TMDS transmitter ). This signal is
tri-stated during a hard reset.

Note :
1) This mainboard provides 2 USB headers on the board
allowing for 4 additional USB ports. To make use of
these headers, you must attach a USB bracket/cable
with USB ports (some models will come packaged with
a USB 4-port bracket-cable). The optionally packaged
bracket will have two connectors that you can connect
to the headers (USB3, USB4). The other end (bracket
containing the USB ports) is attached to the computer
casing.
If you are using a USB 2.0 device with Windows 2000/XP,
you will need to install the USB 2.0 driver from the
Microsoft® website. If you are using Service pack 1
(or later) for Windows® XP, and using Service
pack4 (or later) for Windows® 2000, you will not
have to install the driver.
