Apple IIe Card - Manual (Page 31)

The startup disk is the top icon on the right side of the screen.
4. Double-click the IIe Startup icon to start the program.
The IIe Startup program uses the startup setting in the Slot Configuration
panel to locate a program disk. If a specific slot is designated as the
startup slot, IIe Startup goes directly to the first drive assigned to that
slot. If the startup option is set to Scan, the program scans the slots, in
descending order from 7 to 1. The first startup disk it encounters is loaded
into the computer's main memory, and you see the opening display for the
program on that disk.
If IIe Startup encounters a non-startup disk in the startup drive, you see
the message "Unable to Boot from startup slot." The program enters the BASIC
programming environment and presents the BASIC prompt.
If IIe Startup finds no startup disk in any drive, it enters the BASIC
programming environment and presents the BASIC prompt.
See the section "Changing the Startup Device" later in this chapter for more
information on designating a startup drive.
Going directly to the Apple IIe Option Panel
If you want the Option Panel to open as soon as the IIe Startup program
launches, hold down the Option key just after you double-click the IIe
Startup icon. Keep the Option key held down until the Option Panel opens.
Double-clicking the IIe Prefs file
The IIe Startup program creates and maintains a file called the IIe Prefs
file, which records all the choices you make in the Option Panel. Double-
clicking the IIe Prefs icon causes the computer to switch to the Apple IIe
environment, just as double-clicking the IIe Startup icon does.
When you double-click a preferences file, it reads the preferences from that
file, which is useful if you have more than one preferences file, as
explained in the next section.
Using More Than One Preference File
The IIe Prefs file created by the IIe Startup program keeps track of the
settings you make in the Apple IIe Option Panel. You choose settings to match
the requirements of the Apple IIe programs you run. Normally, one
configuration of card and slot settings is sufficient for performing your
work. However, if you use two or more programs that require different slot
configurations, you can create a separate preferences file for each program.
Each preferences file can maintain the configuration of card and slot
settings appropriate for a single program, so you won't have to change
settings each time you move from one program to another.
Follow these steps to create and maintain more than one preferences file:
1. Start up the IIe Startup program.
Double-click the IIe Startup icon.
2. Open the Apple IIe Option Panel (by pressing Control-Command-Esc).
