This applies only to prototype laptops that were used by software developers before December, 2007.
After firmware q2c28 and before q2d04
- The 'X' game pad key is no longer used during upgrading.
- The Open Firmware ok prompt is available by default in non-secure boot. You will have to press the Esc key during the countdown. It is easy to miss the countdown, but pressing Esc too early can disable the keyboard.
- 'X' game pad key: toggles secure and non-secure boot
- '✓' (check) game pad key: forces a more detailed display while booting; see Startup Diagnosis
- 'O' game pad key: boot from alternate image. At first, laptops have no alternate image.
- Rotate button: display Underwriters Labs safety message
- '◻' (square) game pad key: wipe out user directory and do a factory-fresh install. (appropriate for upgrading machines straight from the factory)
Before firmware q2c28
- Rotate button: play "startup sound" at boot (after q2c27, this key will turn off sound and graphic boot up screen)
- 'X' game pad key: interrupt boot, provide Open Firmware ok prompt. You may have to press the Esc key during the countdown (q2c25). It is easy to miss the countdown, but pressing Esc too early can disable the keyboard.
- 'O' game pad key: boot from backup OS image, for system recovery. (not yet in a stable build)
- Left directional pad: try out "pretty boot" (be patient, early versions show a static boot screen for a long time) (after q2c27, this key will turn off the "pretty boot")
- Right directional pad: try it and see! (tests hardware)
Further, the Autoreinstallation image uses a couple more special game key combinations:
- 'X' and '✓' (check) game pad keys: skip upgrade, just write activation lease to USB key and boot. (if your XO doesn't have a check key, use the 'O' key)
- 'X' and '◻' (square) game pad keys: wipe out user directory and do a factory-fresh install. (appropriate for upgrading machines straight from the factory)
