1�1 Before You Start
Thank you for choosing our product. Before you start installing the motherboard, please make
sure you follow the instrucons below:
• Prepare a dry and stable working environment with sucient lighng.
• Always disconnect the computer from power outlet before operaon.
• Before you take the motherboard out from an-stac bag, ground yourself properly
by touching any safely grounded appliance, or use grounded wrist strap to remove the
stac charge.
• Avoid touching the components on motherboard or the rear side of the board unless
necessary. Hold the board on the edge, do not try to bend or ex the board.
• Do not leave any unfastened small parts inside the case aer installaon. Loose parts
will cause short circuits which may damage the equipment.
• Keep the computer from dangerous area, such as heat source, humid air and water.
• The operang temperatures of the computer should be 0 to 45 degrees Celsius.
• To avoid injury, be careful of:
Sharp pins on headers and connectors
Rough edges and sharp corners on the chassis
Damage to wires that could cause a short circuit
1.2 Package Checklist
• Serial ATA Cable x4
• Rear I/O Panel for ATX Case x1 (B660M-SILVER)
• Quick Installaon Guide x1
• Fully Setup Driver DVD x1

Install an Expansion Card
You can install your expansion card by following steps:
• Read the related expansion card’s instrucon document before install the expansion card into the
computer.
• Remove your computer’s chassis cover, screws and slot bracket from the computer.
• Place a card in the expansion slot and press down on the card unl it is completely seated in the
slot.
• Secure the card’s metal bracket to the chassis back panel with a screw. (This step is only
for installing a VGA card.).
• Replace your computer’s chassis cover.
• Power on the computer, if necessary, change BIOS sengs for the expansion card.
• Install related driver for the expansion card.

2.6 Jumper & Switch Setting
The illustraon shows how to set up jumpers. When the jumper cap is placed on pins, the
jumper is “close”, if not, that means the jumper is “open”.

Pin 1-2 Short:
Clear CMOS data
Clear CMOS Procedures:
1. Remove AC power line.
2. Set the jumper to “Pin 1-2 short”, you can use a metal object like a screwdriver to touch
the two pins.
3. Wait for ve seconds.
4. Aer clearing the CMOS values, be sure the jumper is “Pin 1-2 open”.
5. Power on the AC.
6. Load Opmal Defaults and save sengs in CMOS.
