Keyboard Options
The following keys and key sequences are functional in DOS.
On/Off (Reset)
This key is used to turn the Allegro on and off. The ridge around
the key helps prevent the Allegro from being accidently turned on
without your knowledge (while it is in a backpack, for example). A
hard reset is performed by holding down the On/Off key for about 8
seconds. Release the key when the reboot process begins.
❖ Note: When you turn the Allegro on or off, there is no “beep.” Also, it is
normal for a horizontal line to appear briefl y on the screen.
