To restore the system configuration settings, perform the following steps:
1. Insert the configuration diskette or CD provided with the new system board, and turn on the
computer.
The computer boots from the diskette or CD and prompts you to select the type of system you
are servicing.
2. When prompted, enter the system type and enter the service tag number, which is located on
the back of the computer.
The program notifies you when programming is complete.
3. Remove the diskette or CD and reboot the computer.
4. When the system reboots, press <F2> to enter the system setup program.
5. From the Main Menu, enter the correct time and date in the System Time and System Date
options.
6. Set the Processor Serial Number option to “Disabled.”
7. Press <F10> to save these settings, exit the system setup program, and reboot the system.

To install the microprocessor and heat sink on the new system board, perform the following steps:
1. Using the cleaning cloth supplied with the new system board, wipe the top of the microproces-
sor die to remove any previous thermal grease.
Once cleaned, the microprocessor die should have a reflective shine.
2. Insert the microprocessor into the ZIF socket on the new system board and lower the lever to
lock it into place.
3. Peel off the protective backing (if present) from the enclosed replacement heat sink to expose
the pad of thermal grease.
4. Place the heat sink on the microprocessor and ensure that the bevel on the heat sink covers the
raised portion of the ZIF socket.
5. Replace the heat sink clip onto the heat sink and secure it on the ZIF socket.
The longest side of the clip should be pointing to the front of the appliance.
