Ok

The 'ok' prompt is the Open Firmware menu for the laptop. At this point the laptop firmware is ready to accept commands. The operating system is not running.

There are several methods to get to the 'ok' prompt. The most common is to press the Escape key once when the grey icon first appears after powering on.

The 'ok' prompt is not available if the laptop is secured. If you have tried all these methods, then perhaps your laptop is secured and you need a "developer key". See how to unlock.

Regular

• Shutdown the laptop,
• Watch the display, turn on the laptop, and as soon as the grey icon appears in the centre of the display press Escape key once, and the 'ok' prompt should appear within two seconds.

Novice

This method does not rely on timing. For when you are under stress and doing many things at the same time.

This method sometimes doesn't work for some laptops.

Developer Key Present on Secured Laptop

When a developer key is present on a secured laptop, the timing is different. This is because device and filesystems are accessed before the escape key can be used. The access time varies.

• Shutdown the laptop,
• Hold down the '✓' (check) game pad key and turn on the laptop, a diagram of the game keys should appear with a message Release the game keys to continue,
• Release the '✓' (check) game pad key, and the Type ESC prompt should appear within one to ten seconds,
• Press Escape key once, and the 'ok' prompt should appear immediately.
• press enter to get a fresh 'ok' prompt.

This different behaviour is another good reason to disable-security if the laptop need not be secured.

How do I know it worked?

You should see text on the screen. There should be the word ok with a black rectangle after it.

ok

Press enter, and a new word ok will appear and the black rectangle should move down.

Technical Data

The firmware only checks for the Escape key for a short time during the Startup sound. It is possible for the volume to have been turned down so that you cannot hear the sound, see Startup sound#How to enable to fix.

This 'ok' prompt is called a command line interface (CLI), and the black rectangle is a cursor.

Normally it is hidden, which is why you have to do special things to get to it.
