2-3-1 Glossary
Chipset (or core logic) – A highly integrated circuits which control the interfaces
between the system processor, RAM, I/O devises, and adapter cards.
Processor slot/socket - the slot or socket used to mount the system processor on the
motherboard.
Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM.
PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound
cards, network interface cards, and modems; runs at 33MHz.
ISA - Industry Standard Architecture - a relatively low speed interface primarily used for
sound cards and modems; runs at approx. 8MHz.
Serial Port - a serial data transfer interface typically used for mouse and external
modems.
Parallel Port - a parallel data transfer interface typically used for printers.
PS/2 - a low speed interface used for mouse and keyboards.
USB - Universal Serial Bus - a PnP connect interface used for mouse, keyboards,
scanners, printers, hard drive, DVD/ CDROM and digital cameras.
Sound (interface) - the interface between the sound card or integrated sound connectors
and speakers, MIC, game controllers, and MIDI sound devices.
LAN (interface) - Local Area Network - the interface to your local area network.
BIOS (Basic Input/Output System) - the program logic used to boot up a computer and
establish the relationship between the various components.
Driver - software, which defines the characteristics of a device for use by another device
or other software.
Processor - the "Central Processing Unit" (CPU); the principal integrated circuit used for
doing the "computing" in "personal computer"
Front Side Bus Frequency - the working frequency of the motherboard, which is
generated by the clock generator for CPU, DRAM and PCI BUS.
CPU L2 Cache - the flash memory inside the CPU, normally Intel P4 CPU has 512K or
above, while Celeron M 600MHz has 0K.
10
2-3-2 About Intel Celeron M
This motherboard provides with build in Celeron M 600MHz with 32K L1 cache, 0K L2
cache processor.
The combination of Celeron M 600MHz and 852GM chipsets provide a x86-base low
cost, low power, low heat dissipation and high compatibility solution for mobile
embedded application.
The CPU should have a good ventilation to prevent overheating. If this is not the case,
then make sure the CPU has a sufficient cooling to dissipate heat generate from the CPU.
WARNING!
Be sure that there is sufficient air circulation across the processor’s
heatsink and Chassis FAN is working correctly, otherwise it may
cause the processor and motherboard overheat and damage, you may
install an auxiliary cooling FAN, if necessary.
11
2-4 Install Memory
This motherboard provides one 184-pin DIMM (DUAL INLINE MEMORY MODULES)
sites for memory expansion available to maximum memory size of 1.0GB DDR SDRAM.
•Support 128Mb, 256Mb, 512Mb technologies implemented as x8, x16 devices.
•Non-ECC DIMMS.
Valid Memory Configurations
Bank 184-Pin DIMM Total Memory
Bank 0, 1 (DDR0) 200 /266 DDR SDRAM Module X1 64MB∼1.0GB
Total System Memory (Max. 1.0GB) 1 64MB∼1.0GB
NOTE! Make sure the installed memory are DDR266 SDRAM support 133MHz
memory clock, otherwise the system may hang during startup.
Generally, installing DDR SDRAM modules to your motherboard is very easy, refer to
figure 2-4 to see what a 184-Pin DDR200/DDR266 SDRAM module looks like.
DDR1 (BANK0+BANK1)
NOTE! When you install DIMM module fully into the DIMM socket the eject tab
should be locked into the DIMM module very firmly and fit into its indention
on both sides.
WARNING! For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266-compliant
DDR Modules. When this motherboard operate at 133Mhz, most system will
not even boot if non-compliant modules are used because of the strict timing
issues, if your SDR Modules are not DDR266-compliant, set the DDR
SDRAM clock to 100MHz to ensure system stability.
12
2-5 Expansion Cards
WARNING! Turn off your power when adding or removing expansion cards or other system
components. Failure to do so may cause severe damage to both your
motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively
assign to one use. In a standard design, there are 16 IRQs available but most of them are
already in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Onboard Display Controller
6 * 11 Floppy Disk Controller
7 * 7 Printer Port (LPT1)

11 * 2 IRQ Holder for PCI Steering
12 * 4 PS/2 Compatible Mouse Port
13 N/A Numeric Data Processor
14 * 5 Primary IDE Channel
15 * 1 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.

2-5-3 Interrupt Request Table For This Motherboard
Interrupt request are shared as shown the table below:
INT A INT B INT C INT D INT E INT F INT G INT H
Slot 1 INTB# INTC# INTD# INTA#
IMPORTANT! If using PCI cards on shared slots, make sure that the drivers
support “Shared IRQ” or that the cards don’t need IRQ assignments.
Conflicts will arise between the two PCI groups that will make the
system unstable or cards inoperable.

2-6 Connectors, Headers
2-6-1 Connectors
(1) Power Connector (20-pin block): ATXPWR (CN22)
ATX Power Supply connector is a 20-pins connector comply with Intel ATX
standard. The ATX Power Supply allows to use soft power on with a momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on
the motherboard. When the power switch on the back of the ATX power supply
turned on, the full power will not come into the system board until the front panel
power switch is momentarily pressed. Press this power switch again will turn off
the power to the system board.
