18. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
19. Enter the System Setup program, and ensure that the microprocessor options match the new system configuration (see
"Using the System Setup Program" in your User's Guide).
As the system boots, it detects the presence of the new microprocessor and automatically changes the system
configuration information in the System Setup program. If you installed a second microprocessor, a message similar to
the following appears:
Two 1.8 GHZ Processors, Processor Bus: 400 MHz, L2 cache 512 KB Advanced
If only one microprocessor is installed, a message similar to the following appears:
One 1.8 GHz Processor, Processor Bus: 400 MHz, L2 cache 512 KB Advanced
20. Confirm that the top line of the system data area in the System Setup program correctly identifies the installed
microprocessor(s) (see "Using the System Setup Program" in your User's Guide).
21. Exit the System Setup program.
22. Run the system diagnostics to verify that the new microprocessor is operating correctly.
See "
