During startup, the system will look for previously
saved configuration files. If any are found, a list of available
configurations will be displayed, allowing the user to select an alternate
configuration.
The list will display for up to 30 seconds and, if no user action is taken
within that time, the startup process will continue using the current
configuration.
Any of the configurations can be selected by touching the appropriate line
or, if a keyboard is present, by using the Up, Down, Home or End
keys.
