When a Macintosh is powered-up or Restarted ('booted'),various pieces of Mac ROM and System software examine the keyboard,and take special actions if certain keys are held down. This pagesummarizes the actions.

Booting involves several phases; startup keys take effect atdifferent times depending upon the phase. Sometimes the same keyhas a different effect depending upon which phase it is sensed.Generally, you should hold the indicated keys down until the desiredaction takes place.

CommandBoot with Virtual Memory off
ShiftDisable all Extensions and Control Panels. Release Shift when the message 'Extensions disabled' appears in the welcome box.
SpaceOpen extension manager before loading Extensions or Control Panels. Release the Space bar when the Extensions Manager displays its screen.

Holding the Shift key early in the boot sequence disables allExtensions and Control Panels. Individual Extensions and ControlPanels may disable themselves upon seeing the Shift key laterin the boot sequence, but the timing for this is difficult toachieve! Upon loading, an Extension or Control Panel is supposedto display its icon in the 'icon parade.' If the iconis displayed at boot time, but the Extension or Control Paneldisables itself because the Shift key is held or some error conditionis detected, it is conventional for a red X to be drawn over itsicon.
