Chapter 1 Introduction
The PEB-7605 SERIES all-in-one Mini ITX is designed to fit a high performance Pentium
M / Celeron M 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.
PEB-7605 SERIES support the following processors:
Intel ® Pentium ® Mobile processor Socket 478/479 supporting based on 0.90 micron (CPUID
= 0xh).
Intel ® Celeron M ® processor ULV 800MHz /1Ghz (90nm) supporting based on 0.90 micron
(CPUID = 0xh).
This Mini ITX can run with Intel Socket 478/479 Pentium M / Celeron M processors, and
support DIMM up to 1GB DDR Memory. The enhanced on-board two PCI-IDE interface can
support 4 drives up to PIO mode 4 timing and Ultra ATA33/66/100/133 synchronous mode feature ,
The on-board Super I/O chipset support four serial ports, one SIR (Serial Infrared) port, and one
parallel port. Fourth high performance 16C550-compatible UARTs provide 16-byte send/receive
FIFOs and the multi-mode parallel port supports SPP/EPP/ECP function. three RS-232 serial port
interface and one RS-232 pin herder .Besides, H/W monitor function, , Intel High Definition Audio
as 5.1 surround sound , Hi-Speed USB 2.0 x 6 ports offer up to 40X greater bandwidth over USB
1.1 Also provide dual display function by VGA and LVDS interface..
The Mini-ITX standard makes the PEB-7605 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 20-pin
standard connector is designed to support ATX power function. A feature of CPU overheat
protection will give user more security and stability. All of these features make PEB-7605 SERIES
excellent in stand-alone applications.

2.2.9 External USB3 (USB2.0)
This motherboard provides one USB headers on the board allowing for 2 additional USB ports. To make use of this
header, you must attach a USB bracket/cable with USB ports (some models will come packaged with a USB 2-port
bracket-cable). The optionally packaged bracket will have two connectors that you can connect to the headers (USB1,
USB2). The other end (bracket containing the USB ports) is attached to the computer casing.
Note:
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 drive

Chapter 3 System Installation
This chapter provides you with instructions on how to setup your system. The additional information shows you how to
install CPU/ FAN and memory .
3.1 Socket 478 / 479 Processor
3.1.1 Installing Pentium M / Celeron M Processor
I. The processor socket comes with a screw to secure the processor, please unlock the screw first.
II. Position the CPU above the socket and the gold triangular mark on the CPU must align with
pin 1 of the CPU socket. Then Insert the CPU gently seated in place.
III. Turn the screw to the lock position.
Unlock

socket
Lock
Gold

mark
Note: (1)Do not force the CPU into the socket. It may bend the pins and damage the CPU
(2)The PEB-7605 (On-Board CPU) no need to installed .
3.1.2 Installing Processor FAN Cooler and Heat Sink
i. Tear the sticker off on the bottom of the CPU cooler which combined with the fan and heat sink.
ii. Place the CPU cooler right upon the buckle holes.

(Rearside)
Note: (1)Make sure the CPU fan and heat sink assembly and the CPU top surface are in total contact to
avoid CPU overheating problem that would cause the system to hang or unstable.
(2)The PEB-7605 (On-Board PCU) no need it , which it already have CPU heat sink for fan less.
3.1.3 Main Memory
PEB-7605 SERIES provides 1 DIMMs (184-pin Dual In-line Memory Module) to support 2.6V DDRAM (Synchronized
DRAM) as on-board main memory. The
maximum memory size is 256B~ 1GB with using 256MB/512MB/1GB technology. Supports up to 1 double sided DIMMs at
266/333 MHz. The memory architecture adopts 128-bit data interface to support for x8 and x16 DDRAM(DDR1) device width.
In addition, it only support Non-ECC memory .
For system compatibility and stability, don’t use memory module without brand. You can also use the single or double-side
DIMM .The three DIMMs can be out of order. You can install different size of DDRAM module on DIMM1, or all to boot up
system.
Without out the contact and lock integrity of memory module with socket, it will impact on the system reliability. Follow
normal procedure to install your DDRAM module into memory socket. Before locking, make sure that the module has been
fully inserted into the DIMM slot.
NOTE: For maintaining system stability, do not change any of DDR memory parameters in BIOS setup to upgrade
your system performance without acquiring technical information.
3.2 Installing the Mini ITX
To install your PEB-7605 SERIES into standard chassis or proprietary environment, you need to perform the following
steps:
(1). Check all jumpers setting on proper position
(2). Install and configure CPU and memory module on right position
(3). Place PEB-7605 SERIES into the dedicated position in your system
(4). Attach cables to existing peripheral devices and secure it
NOTE: Please refer section 3.4 to install display and Ethernet drivers and setup your system.
WARNING: Please ensure that your SBC properly inserted and fixed by mechanism. Otherwise, the system might be
unstable or do not work from bad contact of golden finger.

is stored in CMOS RAM whose power is supplied by a battery so that it can retain the setup information even when the power is
turned off. Press Delete when you Power on or Reboot the computer system. (i.e.After the logo appears at the center of the
screen, please press Delete to enter the BIOS setup program). In the BIOS, make sure that everything is working fine before you
try to optimize it for maximum performance.
