a.Wait until the system has completed initializing memory. During initialization, you see the message:

Initializing memory

b. Watch carefully, as you will need to act quickly.

Once the process is complete, the Initializing memory message is erased and the system displays a line similar to:

Boot device: disk2 File and args:

c.At this point, abort the boot process as promptly as possible. To do this, use one of the following methods:

■Hold down the Stop (or L1) key and press A on your keyboard.

■Press the Break key on the terminal keyboard.

■Type ~# in a tip window.

The system should return to the ok prompt.

Note – If the system does not return to the ok prompt, it means you did not abort quickly enough. If this occurs, wait for the system to reboot, force the system to return to the ok prompt, and repeat Step 7.

9.At the ok prompt, type:

ok boot -r

The boot -rcommand rebuilds the device tree for the system, incorporating any newly installed options so that the operating system will recognize them.

10.Turn the control switch to the Locked position, remove the key, and keep it in a secure place.

This prevents anyone from accidentally powering off the system.
