3. Disconnect all ribbon/wire cables from the motherboard, including those for the
keyboard and mouse.
4. Remove all add-on cards.
5. Install a CPU and heatsink (making sure it is fully seated) and connect the
chassis speaker and the power LED to the motherboard. Check all jumper
settings as well.
6. Use the correct type of onboard CMOS battery as specifi ed by the Manu-
facturer. Do not install the CMOS battery upside down to avoid possible
