3.Locate the jumper on the system board (see the preceding figure, “System Board Jumper Locations”).

4.Remove any subassemblies blocking access to the jumper (see Section 3, “Disassembly and Reassembly,” for procedures).

5.Change the jumper setting by moving the jumper to or from the pins as indicated in the jumper settings tables (see “System Board Jumper Settings” in Section 2).

For some functions, a jumper is moved or removed for only a few seconds. The jumper change takes effect immediately, even if the jumper is moved back to its original setting. Check the jumper settings tables carefully and be sure to move the correct jumper so you don’t inadvertently change important settings.

6.Replace any removed disassemblies and the system cover (see Section 3).

7.Connect any peripherals and power cords and power on the system.
