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 Esc.png 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 Esc.png Escape key once, and the 'ok' prompt should appear within two seconds.

This method sometimes doesn't work for some laptops.

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 Esc.png 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.

You might only have needed the 'ok' prompt for a specific task. But there's way more. To learn how to use the 'ok' prompt fully, see Forth Lessons.
