Safety Instructions
Follow these precautions when operating your computer.
1. Always unplug the power cord when inserting any add-on card or
module inside the system.
2. Wear a grounding strap attached to a grounded device to avoid
damage from static electricity. If one is not available, discharge
static electricity by touching the metal case of a safely grounded
object before working on the motherboard.
3. Place components on a level grounded antistatic pad or on the
packaging that came with the components whenever the
components are separated from the system.
4. Keep equipment away from moisture and humidity.
5. Hold all circuit boards by the edges. Do not bend circuit boards.
6. Keep this User’s Manual for future reference.

Chapter 2 Hardware Installation Process
Installing the Central Process Unit (CPU)
CPU Installation
1. Unlock the CPU socket by pulling the locking lever up to a 90-
degree angle.
2. Position the CPU above the socket so that its marked corner (pin1)
matches the corner near the base of the lever.
3. Place the CPU into the socket. (If you cannot insert the CPU easily,
check its orientation and attempt to re-install it.)
Warning! Do not force the CPU into the socket. Doing so will bend
the CPU pins and damage the CPU.
4. Secure the CPU to the socket by lowering the lever and locking the
lever in place.

Installing Memory Modules
1. Push the white retaining clips on the memory socket outwards.
2. Match the notches on the contact edge of the memory module to
the ridge in the memory socket.
3. Insert the memory module vertically into place. When properly
inserted, the white retaining clips will move inward to lock in the
module.
4. Repeat the installation process to add additional modules.

Connecting IDE and Floppy Disk Cables
Connecting the floppy disk ribbon cable into the motherboard. The side
of the cable with the red stripe needs to be inserted into the Pin1 side of the
floppy disk connector. Pin1 is marked with a white triangle.
Connecting the IDE ribbon cable into the motherboard. The side of the
cable with the red stripe should be inserted into the Pin1 side of the IDE
connector. Pin1 is marked with a white triangle.
Note: The motherboard has two IDE connectors. You can connect
IDE devices to any of these connectors.
