Unscrewing the main system board screws

5. If you do not have a second CPU option, remove the two remaining

screws, as seen in Figure 8–4. Skip this step if your configuration
includes a CPU option board.

6. Grasp the the system board at its top and bottom centers, above

and below the interboard connectors, as seen in Figure 8–4. Gently
pull to dislodge the system board from the computer chassis
connector.
