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.
