Hardware Notice Guide
1. Before installing the power supply with this motherboard, please attach the 12V/DC
( 4 pin connector )of the adapter to motherboard first.
After that, plug the adapter power to AC outlet.
Always normally shut down the computer before you move the system unit or remove
the power supply from the motherboard.
Please unplug the 12V/DC ( 4 pin connector ) of the adapter from motherboard first.
Then unplug the adapter from the AC outlet.
Please refer to procedure from the photo 1
2. There will be high possibility to burn out the CPU if you change/ modify any parts of the
CPU cooler.
3. Please wear wrist strap and attach it to a metal part of the system unit before handling a
component.
You can also touch an object that is of ground connection or with metal surface if you don't
have wrist strap.
4. Please be careful when you handle this product. Pay attention to & don't touch the
sharp-pointed components at the bottom PCB .
5. Please pay attention to this: Remove or change any components form the motherboard
will VOID the warranty of the motherboard you purchased .
6. Before you install/remove any components or make any jumper setting on the motherboard,
please make sure to disconnect the power first.
( Please follow the instructions as of this guide )
7. Please only use single sided Mini PCI card, do not use the double sided Mini PCI card
which is not suitable.
8. This does not support 16 bit mini PCI card
9. Please follow this instruction carefully when using the "POWERON after PWR-Fair" function.
When the DC power adaptor runs out of power, unplug it from the DC current;
when power returns plug it back in only after 5 seconds. If there is a power outage,
unplug it from the AC current, when power returns plug it back in only after 30 seconds.
Otherwise it will cause system locking or serious damage.
Remark 1:
Always insert/unplug the 12V/DC ( 4 pin connector ) horizontally & directly from the
motherboard.
DO NOT twist the 12V/DC ( 4 pin connector ) gently, it is designed to fit snugly .
Moreover, erratic pull / push testing with the DC Jack might cause the unpredictable
damage to the component & system unit.

Hardware Installation
This chapter provides the information how to install the hardware of MI945A.
Please follow section 1-6, 2-1 and 2-2 to check the delivery package and unpack
carefully. Please follow the jumper setting procedure.
Chapter-2
2-1 Unpacking Precaution
The MI945A board has been well packed with an anti-static bag to protect its
sensitive components and circuitry from damage due to static electric discharge.
You should follow these
steps to protect the board from the static electric
discharge whenever you handle the board:
1. Ground yourself by a grounded wrist strap at all times when you
handle the MI945A.
Well secure the ALLIGATOR clip of the strap to the end of the shielded wire lead from
a grounded object. Please put on and connect the strap before handling the
MI945A for harmlessly discharge any static electricity through the strap.
2. Please use anti-static pad to put any components, parts, or tools on the pad whenever
you work on them outside the computer. You may also use the anti-static bag instead of
the pad. Please ask your local supplier for necessary parts on anti-static requirement.
3. Do not plug any connector or set any jumper when the power is on.
1. Do not touch the board or any other sensitive components without all necessary
anti-static protection.
2. Please pay attention to the voltage limitation of DC-IN12 V 5 %.
Overuse of DC-IN voltage limitation or change to another power adapter
( not provided with this system ) will VOID warranty.
NOTE!
